Today, we’re dipping our toes in the waters of Elite’s top-end VSX-LX805 AV receiver (MSRP $2,999) with an in-depth review, dissecting its build quality, performance characteristics, specialties, and – yes – a few warts. Much like Integra-branded receivers released in 2023, the LX805 was conceptualized by US-based design leads who were particularly tuned into the wants and needs of enthusiasts and custom integrators. They listened to those communities and pushed hard internally to ensure the LX805 and its mates hit the street with appeal and technical pizzazz.

The LX805 wasn’t originally intended to slot as Elite’s top model. That role belonged to another design that never made it to production. You wouldn’t know it, though, because this receiver proudly flexes plenty of flagship-level muscle. Take its four subwoofer outputs, for instance. Unlike many receivers, these are split into two independent channels, allowing for precise tuning and time alignment for truly flexible subwoofer placement. Pair that with its dual calibration options – Dirac Live with Bass Control and MCACC Pro – and you have a system that caters to advanced users as well as those seeking a simpler setup. Of course, there are many other tech features and physical elements… so let’s dive in.


Physical Look and Feel
full?d=1737562186.jpg


Last year, we uploaded an unboxing video of the LX805, so if you’d like to hit pause and watch this beauty rise from its packaging, you can do so here. If you’re impatient and prefer to keep reading, know that the receiver arrives in grand fashion. My sample shipped triple-boxed in packaging designed from the ground up. The main box, adorned with striking graphics emphasizing the receiver’s advanced technology, contained a gloss-black Elite-branded accessories container—a fun nod to the brand’s iconic heritage – and the receiver, masterfully cocooned in custom styrofoam and protective wrap.

If you're a buyer who appreciates high-quality packaging, you'll be pleased.

The LX805 weighs nearly 50 lbs, making it hefty to lift. While it didn’t give me issues, you may want to recruit a friend for removal and placement. It’s also a sizeable piece of gear, standing at 7.3” tall and reaching 18.4” in depth. Be sure to read the measurement specs, add some extra space to account for any cables you plan to insert into the back, and confirm that the receiver will fit in your allotted space.

Much of the LX805’s weight comes from its Class A/B power section, which delivers 150W of power across 11 channels. That’s ten more watts per channel than Onkyo’s RZ70 and more than enough muscle to drive most tower and bookshelf speakers. Under the cover, the receiver’s internals drip with quality and organization. One feature you’ll immediately notice is four fanned heat sinks positioned on either side of the reference power transformer. These sinks are custom-molded and exclusive to some Elite and Integra models. For those of you wanting evidence of brand identity, Integra's sinks feature a sleek silver finish, while Elite's showcase a bold and striking black. While trivial, that kind of attention to detail is sure to appeal to hardcore fans of the brand.

To help with cooling, the LX805 has two oversized fans seated directly under its heat sinks. Fans, you say? Can't they get noisy? Yes, fans can, but it just so happens that the LX805's operate whisper-quiet, so there’s no need to worry about added noise.

full?d=1737562185.jpg


With all that amplifier power and attention to airflow, you might wonder how warm the receiver gets during extended heavy use. To test, I placed a full-sized Trinnov processor on top of the LX805, pushed the receiver hard for several hours, and then took measurements. I found external surface temperatures of 102°F (top) and 82°F to 90°F (various areas on the front, back, bottom, and sides). So, things can get quite warm, but I found nothing concerning here. Do make sure you give the receiver room to breathe, though – I wouldn't suggest locking it away in a closed cabinet.

Physically speaking, the LX805 is a head-turner, sporting features like a throwback orange LED display, smooth lines along the edge of its body, and tight radiuses on its corners. You’ll also find a brushed metal faceplate, large machined knobs that turn with a weighted feel, and a soft-touch drop-down panel capped in brushed metal. Truth be told, this receiver aligns perfectly with my aesthetic preferences, offering a forward-facing appearance that’s refreshingly classy.

Unfortunately, physical feel goods don't extend to every aspect of the LX805. Looking closely, you’ll find areas where cost cuts were made. For example, the included backlit remote carries a faux brushed metal face and feels plasticky and cheap in the hands. The receiver’s feet are also molded plastic, though they nearly fooled me; I had to remove a foot to confirm its material makeup. While neither of these is a deal breaker, I was shocked to find standard black and red speaker posts mounted on the backside. Given the LX805’s flagship status, I’d expect something of higher quality.


Distinctive Features
full?d=1737562186.jpg


Before we talk setup, let’s highlight some of the LX805’s more unique features that audiophiles may find appealing. To start, the receiver offers Elite's exclusive Precision Quartz for File-based Audio or PQFA. PQFA is used when media is sourced via network, USB, and Bluetooth. It stabilizes the clock signal during digital audio playback, purportedly reducing invasive jitter. This feature isn't found on Onkyo or Integra receivers.

The LX805’s AV Direct Mode also improves sound quality by limiting digital circuit activity associated with network, Bluetooth, and USB inputs. This can be engaged when listeners source audio from external devices connected to the LX805 via analog and digital inputs. In a similar vein, the receiver also has an HDMI Audio Exclusive Mode that shuts off the video side of the receiver’s HDMI Input 1 jack, eliminating another potential source of noise to the audio signals incoming through HDMI connections.

The Elite also carries two notable industry certifications that cater to audio functions. The first is Works With Sonos, which means the LX805 can integrate with an existing whole-home or single-speaker Sonos system. Essentially, the receiver can be added to and controlled through the Sonos app. So, the need to fidget with multiple apps is eliminated, and owners can make track selections and control volume levels all within Sonos' app architecture.

The other certification is Roon Ready, which means the receiver integrates seamlessly with Roon using the Roon Advanced Audio Transport (RAAT) protocol. This allows for bit-perfect playback, high-resolution audio support, multi-room synchronization, and complete control through the Roon app. Don't confuse Roon Ready with Roon Tested, which applies to devices verified to work with Roon but typically rely on alternative playback protocols like AirPlay or Chromecast – the LX805 gives you access to the good stuff.

Set-Up
full?d=1737562186.jpg


The LX805 marks a new chapter in graphical user interface design for Elite products, introducing a clean and user-friendly layout. It looks great and doesn't take much effort to navigate. First-time users, particularly those new to AVRs, will appreciate the intuitive onscreen instructions that guide you through essential setup tasks, like connecting to WiFi and configuring a room’s speaker arrangement, and some of the minutiae like hooking up HDMI eARC and performing a sound check to ensure speakers are properly connected to the correct terminals—the latter of which caught a mistake I made as I wired a 7.2.4 speaker array. Yes, even seasoned pros can cross their wires!

For me, the Elite had Wi-Fi set up and running in about 40 seconds, aided by integration with my iPhone. Of course, we've all experienced maddening problems with Wi-Fi, and the LX805 has tools to ease the pain. Within the menu system, you'll find a built-in network connection check that verifies MAC and IP addresses, performs a gateway ping, and runs an internet service test— all handy tools that are lightning-fast in response times.

Owners have two calibration systems at their disposal to fine-tune audio performance: Pioneer’s proprietary MCACC Pro and the highly regarded Dirac Live. Both can be used with the microphone included with the LX805. However, if you want to extract the absolute best from Dirac Live, consider investing in a miniDSP UMIK-1 microphone and running the calibration on a PC or Mac. For this review, I tested both MCACC and Dirac Live, along with Dirac's optional Bass Control module, using the included mic and free Pioneer Remote app (iOS, Android) to get that "out-of-the-box" user experience.

MCACC is definitively the weaker of the two calibration options, making it best suited for a quick set-up focused on basic tasks like setting speaker distances and channel levels. Pre and post-MCACC measurements revealed that the software actually degraded my system’s overall response. Bass frequencies were left virtually untouched, while frequencies above 200 Hz exhibited less flatness after correction. On the channel leveling front, MCACC managed to align the front left, right, and center channels within half a decibel of each other but struggled with the remaining channels, many of which were off by two to three decibels from reference.

My advice: skip MCACC and proceed directly to Dirac.

Dirac Live is a standout feature and a significant selling point of this receiver. Surprisingly, you can actually achieve impressive results with the included microphone and the free app, not to mention running Dirac with these tools is reasonably accessible to first-time users. If you're a true green-to-the-core newbie, you might need to ask for help on our forum. But I'm fairly confident that most will trial and error their way to good results.

Out of the box, Elite provides the full-bandwidth version of Dirac Live, which enables frequency corrections beyond 500Hz. For those looking to take things to the next level, Dirac Live Bass Control is available for an additional $299. It offers precise control and optimization of your subwoofers and is a recommended investment for serious enthusiasts.

Note, if you’re considering the LX805’s less expensive sibling, the LX505, Dirac Live Bass Control is not available as an add-on option.

As you can see in the images below, I crafted an aggressive house curve using the free Dirac tools available within the app. For whatever reason, I had difficulty taming decibel levels in the 10 to 20Hz range, so if the receiver were staying in my rack, I'd use a calibrated microphone and a laptop to dial things in a bit better. That said, the core of my review profile delivered plenty of clean punch during demo sessions, so I was happy.

One of Dirac’s advantages is its ability to correct the impulse response of the audio system. This addresses time-domain issues like phase and timing errors, resulting in a more cohesive and accurate soundstage. As reflected in my before-and-after Room EQ measurements, Dirac effectively tightened up the response, enhancing clarity and coherence.

A notable limitation of the LX805 is its ability to save only three Dirac profiles derived from a single set of measurements. In addition, you can’t store both MCACC and Dirac profiles simultaneously, which is something I'd consider to be an "enthusiast inconvenience." Receivers capable of storing a broader range of profiles typically cost thousands more, so I wouldn’t brand this as a major drawback – most owners probably won't care.


Performance
full?d=1737562186.jpg


So far, so good. Right? From unboxing to handling the receiver and running set-up procedures, the LX805 had practically won me over. It’s a device that strikes a perfect balance – offering enough complexity and advanced features to satisfy seasoned home theater enthusiasts while remaining approachable and intuitive for newcomers or those less tech-savvy. While I found a few spots in the menu system and user manual that could benefit from more detail, Elite’s design team truly knocked it out of the park from a usability standpoint.

That brings us to playback, where I'd like to begin by discussing an unsightly wart: the LX805’s built-in Bluetooth Transmitter. I have to admit, seeing "Bluetooth Transmitter" listed in the specs kicked my expectations into overdrive, leading me to assume I'd experience a process that was easy and reliable for both movies and music. I was expecting a lot, and in my case, those expectations were well off the mark.

The most significant issue was getting the LX805 to recognize my earbuds, which included Atlantic Technology’s TSW-1 and Bowers & Wilkins Pi8. The receiver became stuck in pairing mode during several attempts, effectively freezing and becoming unresponsive. The only remedy was to power down the unit, restart it, and try again.

Following one successful pairing attempt, I tried sourcing tunes through Spotify Connect. Activating Spotify instantly disconnected my earbuds, sending me back to the frustrating cycle of pairing. To make things worse, my system also lost all audio output capabilities after the buds went dark. To get everything working again, I had to power down the receiver, restart it, and then cycle between inputs before the speakers would play any sound.

It became complexly frustrating and not something I'd want those less technically inclined to troubleshoot.

Did I ultimately get the transmitter to work? At times, yes... with music, but I was never able to reliably stream movie audio. Any audio linked to video content was laggy and full of connection issues. So, from my experience, the Bluetooth Transmitter is a feature worth ignoring.

The rest of my time test-driving the LX805 was pure fun. For this review, the receiver drove a range of GoldenEar Technology speakers (Triton One.R mains, Triton Reference Center, Invisa in-walls for surround and rear) along with SVS Elevation height speakers and dual SVS SB16 Ultra subs. Sources included Apple TV 4K, Kaleidescape, and a Panasonic UB9000 universal disc player.

Movie content with the LX805 was exceptional, offering a deeply immersive audio experience. Lone Survivor (4K, DTS-HD MA 5.1) has become one of my demo films, and upmixing its audio track using the receiver's built-in Auro-3D Auromatic engine produced fantastic results. I focused on two standout scenes:

The first begins with actor Alexander Ludwig reciting the Frogman’s Ballad as helicopters arrive to pick up Navy SEALs and transport them into the mountains. This scene is packed with dynamic energy, and it really highlighted the correction capabilities of Dirac Live and Bass Control as compared to MCACC. While MCACC testing produced a serviceable audio experience, Dirac Live took it to another level, expanding the soundstage beyond the room’s boundaries and sharpening the center image with notable precision. Bass during this scene is widely varied, and the LX805 conducted a low-end presentation that was nuanced and impactful, seamlessly integrating into the mix.

The second scene, the opening moments of the battle in the mountains, reinforced the LX805’s ability to recreate incredible atmospherics. The speakers handled reference-level playback effortlessly, producing crystal-clear audio that filled the room with power and detail.

Next up was Devotion in 4K with Dolby Atmos. The final battle scene and subsequent plane crash are loaded with immersive activity, and the LX805 brought the scene to life. Sound pans were precise with pinpoint accuracy, and the film's action sequences filled the front soundstage with thunderous audio. Even the quiet, more subtle moments—like the whispers of wind or soft dialogue—were impressive. And let's not forget about the bass, which was exceptionally well-managed: impactful without feeling bloated, blending seamlessly with the rest of the sound.

I usually avoid reading other reviews before evaluating equipment, but a forum member pointed me toward one write-up that claimed the LX805 tended to render dialogue as flat. To investigate, I played one of the films mentioned in that review – Interstellar (4K, DTS-HD MA 5.1) – and found nothing objectionable. Dialogue clarity and texture sounded perfectly fine on my system.

To dig deeper, I turned to Pulp Fiction (4K, DTS-HD MA 5.1) and its iconic Jackrabbit Slim’s twist contest. From Vincent Vega chatting with Mia Wallace through her home's intercom system to conversation in the lively ambiance of the restaurant, dialogue came through rich and engaging. I couldn’t detect any issues here, either.

I suspect – but am not 100% sure – that any dialog complaints may have stemmed from differences in room correction and how it’s been applied. So, take that for what it's worth.

One limitation worth noting—and one that some potential owners might be curious about—is the playback and upmixing restrictions for Dolby-encoded content. With Dolby, you’re limited to native playback or Dolby modes, such as Dolby Surround or Dolby Atmos. In contrast, DTS-encoded content, including DTS-HD MA and DTS:X, is more flexible, allowing you to choose between Auro-3D or Dolby mixers.

I was pleasantly surprised to find in-depth onscreen audio and video details available by pressing the remote’s “Info” button. On the audio side, you can quickly identify how audio is being sourced, along with native codec, channel count, and resolution information. You can also see what, if any, processing is engaged, the output channel count, and what type of room correction is being used. Video details are equally impressive, showing source content resolution, frames per second, color depth, and high dynamic range information. I mention this because enthusiasts often want to confirm what kind of content is being sourced and how it’s being presented — the LX805 delivers on all fronts.

For stereo testing, I reached for John Bellion's The Human Condition, Norah Jones' Come Away With Me, Pink Floyd’s remastered Dark Side of the Moon, and a collection of favorite tracks ranging from bass-heavy electronica to the subtleties of ambient pieces like those from Aphex Twin. These reference tracks cemented my opinion of the LX805’s overarching competency with both 2-channel and multi-channel audio, with a positive nod toward Auro's Auromatic upmixing. It sounded great.

There were moments when music presentations appeared slightly crispy or subtly jagged on the higher end of frequencies. I switched between Dirac and native playback, and that trace signature remained, so I'm left to assume the LX805 has a taste of innate brightness to its sound. However, I'll be the first to admit that my observations may have been my ears and brain picking up on details that have always been present in some tracks. I certainly heard nothing cringeworthy, and the receiver is definitively built to sing boldly and proudly. In fact, the LX805 confidently pushed volumes to reference levels without running out of steam or succumbing to distortion.

This, folks, is one fine piece of equipment.

Conclusion
full?d=1737562185.jpg


What we have in the LX805 is an impressive package that’s sure to please. Its design is thoughtful, its construction is impressive, and its performance factors are on full display the second you plug it in.

I’m a new Pioneer owner, and I’m still in the process of setting it up, including running Dirac (again…now with better mic).
So far, the equipment has made a really good impression on me, but I’m honestly a bit shocked by the fan noise. Unlike other brands like Marantz, the fans don’t just kick in when things get warm—they run all the time.
It’s like listening to music or watching a movie with the background hum of a computer always on :/
Does anyone know if there’s a way to configure the fans so they only turn on when the unit actually heats up? Is there any setting for this?
Thanks in advance

Have you noted where the main source of heat is? - are talking the power amp heatsinks, or the HDMI & DSP chipsets?

Are your speakers very demanding? (low impedance? requires high current? )

I have not noted reports of fan noise in the various forums discussing the RZ70, DRX8.4, LX805....

The only fan that is still spinning is above the HDMI board, but you can't hear it because it has a low speed.
The other fans have never started in 2 years. I have an 805.

So for your use case - there appears to be no need for external forced air circulation...

Nothing is overheating. The fans are running all the time, but not at excessive speeds (as they do, for example, during MCACC calibration).
That is exactly the problem.

I have very good, sensitive hearing, so the operation of the fans is clearly audible to me. During movie watching, especially in quiet scenes, the fan noise becomes disturbing — instead of silence, there is silence plus the constant hiss of the fans.

My current setup is as follows:
AV Receiver: Pioneer VSA-LX805
Front speakers: Klipsch RP-280F
Center speaker: Klipsch RP-504C II
Surround speakers (rear): Klipsch R-51M
Height / ceiling speakers: Klipsch Icon VS-14
Subwoofer: Klipsch R-112SW

805 is properly ventilated, not enclosed, and operates within normal temperature ranges. Despite this, the fans are always active, which significantly affects the listening experience during quiet passages:/
 
Yep Nothing is overheating. The fans are running all the time, that’s the problem.
Any ideas ?

Nothing obvious...

My Integra DRX3.4 (same as LX305) rarely turned on its fans... and (or) when it did they remained at very low speed, and were not audible to me! (you can monitor the fan status on the status screen of the web interface)

I would be looking at its operating temperature as the fans are supposed to be thermostatically operated - so if the temp is low, they should turn off....

Also whether they are off when the AVR is cool after just being turned on, and then come on after a certain amount of time in use...or at certain volume levels?

My experience with that generation of PAC devices, and my reading of related forums online, is that the fans should by default be off until the temperature rises to some (unspecified) trigger point.
 
I am extremely skeptical that Dirac ART will be added, due to strong antipathy at Onkyo for that technology, and PAC goes where Onkyo steers.
Well, Onkyo (Gentex) announced new products & developments at CES 2026, which are supposed to have Dirac ART implemented (additionally to other implementations). The product to look at would be Onkyo TX-RZ71...
Its technical design feature new DACs and a radical change to the front panel looks ;)
Coming Onkyo AVRs seem to feature (still) Class A/B amps, although newly designed Class D amps are catching up strongly in sound quality (featuring PFFB loops etc).and have better efficiency.
Sorry, that Pioneer no longer belongs to those brands listed...

All of the newly announced products are concepts, not commitments. It's one thing to claim Dirac ART capability, and another to implement it, especially when the engineering team doesn't want it in the first place.

In 2015, Onkyo laid off all of the Onkyo and Pioneer engineers who had developed their most superlative products, leaving a team that was extremely reticent to doing anything that requires innovation. That's why Pioneer, Elite, Onkyo and Integra have all shared a common platform since 2016, and saw almost no changes to those lines except evolutionary ones, and eventually retrograde actions such as eliminating Class D amplification across all brands in favor of generic A/B amplifier designs that were quite mediocre in sound quality.

In the three years leading up to the 8.4, RZ70 and 805, we were constantly being told that there was no processing power available for the Dirac Live multisub plug-in, or Auro-3D, or 16ch processing, or room in the chassis for 16ch of Class D modules. All of these (with the exception of 16ch processing which demanded an entirely new CPU) were proven false right up to the first production deadline. Because Onkyo continuously dragged their feet or outright lied in the face of evidence to the contrary, we lost out on Class D in those models. Because Onkyo had neglected to R&D new CPU architectures, we lost out on including Dante as well, among others. The list of things Onkyo should have stayed on top of but didn't is as long as my arm.

Class D amplifiers have been audiophile level for decades now, since the earliest iterations of ICE, and are continually improving, so not sure where you're going with that.

Sorry, but English is not my native tongue ;)

Concepts. commitments, products ? All of these are pointing into the future of Onkyo/Integra (late 2026, early 2027 ?), not Pioneer right now.
Class D amps have been on development for several decades and Pioneer was one of the early proponents of this technology in their AVRs, although most buyers / listeners reacted negatively to the proposed "sound quality" of those early adopters. Except for a few "followers" this and several test results might have caused a reduction of potential buyers and have been the reason for those buyers missing finally (at least for Pioneer).

This is mainly the reason, why almost all manufacturers switched back to Class A/B designs for their power amps in AVRs in the past, although efficiency and space constraints took their toll on those designs.
Class D amps have matured lately by new designs (Purifi, Hypex NCore, PFFB etc.) into really listenable power amps independent of most speakers at home.
I can't comment on those mentioned cost and time constraints, but something seems to have changed by now: Onkyo / Integra was bought, Pioneer AV left in the "dark" without a representative.
I don't know, if there will be any new products by Onkyo / Integra but the future for Pioneer AV at least looks mood right now, doesn't it ?

That is my point of view, Yours seem to be different ;)

PS.: The Pioneer VSA-LX805 seems to be a rather "great" product, but I am still hesitating to buy one even at those reduced prices because of the now missing support and service...
I bought some time ago an Onkyo TX-RZ70 without hesitation at a higher price, but a Pioneer AV product right now ?

I don't know, if there will be any new products by Onkyo / Integra but the future for Pioneer AV at least looks mood right now, doesn't it ?

That is my point of view, Yours seem to be different ;)
"Class D amps have been on development for several decades and Pioneer was one of the early proponents of this technology in their AVRs, although most buyers / listeners reacted negatively to the proposed "sound quality" of those early adopters. Except for a few "followers" this and several test results might have caused a reduction of potential buyers."

I was a Pioneer product developer and marketing strategist at the start of our partnership with ICE, and participated in the first private and public demonstrations. Without exception, all of the major critics we demonstrated ICE to lauded its performance. ICE quickly became Pioneer's go-to step-up technology for consumers and criticsfor years to come, and the last Class D design (not ICE) was quickly adopted by Onkyo from 2016 until 2021. Pioneer's consumer base were rabid supporters of Class D.and were incredibly vocal when we stopped including it. Meanwhile ICE continues to show quite strongly in the Class D space, and is highly regarded in the amplifier market.

"This is mainly the reason, why almost all manufacturers switched back to Class A/B designs for their power amps in AVRs in the past, although efficiency and space constraints took their toll on those designs."

Patently false. "Almost all manufacturers" weren't even considering, let alone including Class D until well after ICE hit the market. More manufacturers began adopting Class D in the years following the introduction of ICE; the rapid decrease in cost-to-build (high-power Class D is more cost-efficient per channel than high-power AB) was a powerful motivator. Purifi, for example, exists because it uses former ICE engineers.

My "opinions" are based on 25 years with both Pioneer and Onkyo, the latter for which I was global brand manager and product developer for Onkyo, Integra, Pioneer and Elite.

I loved the roll out of new generations of Class D for Pioneer products (at least it was marketed that way). It made Pioneer/Elite seem so edgy and innovative. If you were buying in, you were buying something special.
 
I would like to honor Your engagement for Class D amps, but not everyone seem to have shared Your sentiment towards Class D amps at that time. Many had their own negative impressions, especially "audiophiles", concerning the sound quality of Class D amps at that time. This probably caused many or most manufacturers to revert their positions and change their amp design "back" to Class A/B...

You keep talking about "reverting" and "many". Aside from Aragon, which had already disappeared by the time Pioneer co-developed ICE with Philips, what other brands were using Class D at the time? It was a rarity because of a) the high initial R&D and investment costs in those early years (Pioneer and ICE spent 10 years developing ICE Power before it was ready), and b) the baseless prejudice against it by a minority of the audiophile community which (as too many are today, sad to say) are much more interested in specs than in how something sounds and makes them feel. The number of brands experimenting with Class D in the 90s and early aughts could be counted on a few fingers on one hand, and there was never any "reverting" taking place. Instead, those brands continued to improve upon Class D technology.

You actually don't know what my sentiment towards Class D is, so allow me to clarify: Class D, like A and AB, and the rest of the amplifier alphabet soup, is a tool to achieve a goal. It's everything else associated with an amplifier that creates a "good" or "bad" sound. Show me a fantastic AB, and I'll show you an equally phenomenal Class D, and vice versus. For the record, my current reference system uses a hybrid Class A/AB design. While I am very proud of the tuning we did on the new AB amp design in the 8.4, RZ70 and 805 AVRs (and they sound significantly better than the ABs used in past generations of Pioneer, Onkyo and Integra), I am using them as preamps to feed XTZ Class D amps which happen to incorporate modules by ICE. I'm driving some large and very inefficient speakers that require more push to sound their best.

At trade shows, there was inevitably that "one guy" who would parrot whatever he read in the magazines. He would get nose to nose with me and say "I hate Class D!" like he expected me to get defensive and start a fight. To which I'd shrug and reply "So? See those amps and receivers over there? Those are all AB. Help yourself." The point is that not all ABs sound the same any more than all Class Ds sound the same, and one is never inherently better than the other. But some people don't want to hear facts. Some people don't want to reconsider positions that probably aren't theirs to begin with.

There did seem to be a sentiment that D didn’t sound as warm (?) as A/B.

I don’t think I could walk into a room, blind, and tell a difference

Yes, that was the common description in the early days.

When Aragon released it's first 2ch Class D amp, that model raised a lot of eyebrows among the Class D naysayers. Pioneer and ICE collaboration was the talk of the town. That's a demo I'll never forget: everyone who was anyone in the audio critic world, around 30, were assembled to hear our AVR running EX speakers by Andre Jones in a 9.2 configuration. Every single journalist was demanding a sample of their own to evaluate, saying they'd never heard Class D sound like that before.

Good times. History.
 
Nothing like four hour calls with Japan and Pacific market counties at midnight EST to discuss power cords!

Was the last iteration marketed by Pioneer called Class D3? Am I remembering that correctly?

From your perspective, was it actually a healthy improvement over previous versions? I remember PR material talking about shorter internal pathways.... perhaps improved multichannel performance. But, that was a while ago. 10... maybe 12 years?

In the beginning was ICE Power, and it was good. Then there was a period where Pioneer engineers independently redesigned the ICE modules and called the result D³ (why not D²? that was a marketing ploy)

Anyway, I remember there being susprising confusion on the Onkyo side of things after they shanghaid Pioneer's Home Entertainment Division that all Class D amplifiers are digital amplifiers (they're not), which immediately filled me with serious foreboding. 🫤

D³ shortened the signal path considerably vs ICE Power, also improving heat dissipation, and sounded...different. Maybe a bit more dynamics and warmth. Anyway, that's what ended up in select Pioneer, Elite, Onkyo and Integra models until 2021, after which it was AB for everything.

There should be a few diagrams of D³ vs ICE in that enormous data dump I sent you. 😉
 
I was just thinking it's probably in there... and just a heads-up: we've created a section for all that information on the back end, and I'm beginning to work through it!

That might not mean anything to forum members, but something pretty cool is coming!

Feel free to reorganize it however you think it would be easiest to navigate.
