- Looking to breathe new life into your vintage audio system?

This high-performance DAC bridges the digital and analog worlds, delivering audiophile-grade sound with zero compromise.
In the ever-growing landscape of digital-to-analog converters (DACs), it takes something truly unique to stand out. That’s exactly what the Essence HDACC II-4K manages to do—not by chasing audiophile bragging rights or spec sheet supremacy, but by solving a real, everyday problem in a smart and elegant way. This is a DAC designed not just to impress, but to fit—into your home, your system, and your lifestyle.
A Long-Standing Problem Solved
Several years ago, I received a Jolida tube integrated amplifier as a gift—a beautiful piece of kit that sounds sublime when paired with my phono stage and turntable setup. The downside? It lacked a straightforward way to connect a television to my stereo speakers. As someone who doesn’t watch a ton of TV upstairs but still values audio quality when I do, this presented an annoying limitation.An attempt to work around the issue using a Bluesound Node and optical output from the TV ended up being more trouble than it was worth. The constant need to manually switch sample rates between music and video sources became tedious, so I gave up. A Sonos soundbar filled the gap, albeit uninspiringly.
Enter the Essence HDACC II-4K
When Essence reached out about reviewing the HDACC II-4K, I was initially skeptical. DACs, by nature, are tricky to evaluate because many already offer excellent audio quality. What truly matters—especially in real-world use—is how they integrate into your system. The HDACC II-4K, however, offers a killer feature set that immediately caught my attention: four HDMI 2.0b inputs and one HDMI output.This means you can route multiple modern digital video sources directly into this DAC and feed audio out to your existing analog gear—yes, even that tube amp you refuse to part with.
Setup and First Impressions
Setup was mostly straightforward. The unit is compact but solidly built, with a reassuring heft and a clean design. When I first played music from Apple Music via Apple TV, the sound was distorted—but that was user error. I had missed a setup step: enabling variable output volume, maximizing it, and locking it in. Once corrected, the distortion disappeared, and the audio came to life.Using Beth Waters' “White Dogs in the Moonlight” as a test track revealed excellent clarity, dynamic range, and low-end response. This DAC doesn’t just pass audio—it presents it. And importantly, it does so without requiring constant tweaking or supervision.
Features That Matter
Here’s a rundown of what the HDACC II-4K offers:- Four HDMI 2.0b inputs and one HDMI output with 4K video pass-through
- USB 2.0 audio input, optical and coaxial I/O
- Analog input with onboard ADC to digitize vinyl or other sources (up to 384kHz)
- Built-in headphone amplifier
- RCA and balanced XLR outputs
- Support for native SACD, DSD 256, and sample rate conversion up to 384kHz

Real-World Performance
What really sets the HDACC II-4K apart is how effortlessly it bridges modern digital sources with classic analog gear. HDMI audio from Apple TV, YouTube, Blu-ray rips via Plex, and even live TV through the HDHomeRun all passed through with zero sync issues. Lip sync was flawless, and the experience was seamless—finally solving a problem that had persisted for years.One small gripe: the front display can't be turned off. While not a dealbreaker, it does mean you'll need to place the unit somewhere that avoids distracting light during movie nights.
Bonus for Vinyl Lovers
Though I didn’t test this feature personally, the HDACC-II 4K does have the ability to digitize vinyl through the analog input could be a huge plus for collectors. The mini-plug ADC input allows for high-resolution transfers of your rare records—handy if you want to preserve them digitally without complex gear.Final Thoughts

For Apple TV users in particular, this is arguably the most elegant, functional solution currently available.It's rock solid, intuitive, and thoughtfully designed for people who just want to listen—not endlessly fiddle with settings.
