Awful news, very sorry for John's loss!

Nice cables, decent price for an active cable.

I would guess the amp will go before the speaker... The reason boosting a true null is a bad idea is that it is caused by the direct sound, D, being cancelled by the reflected sound, R, so you get D - R = 0. If you amplify by 10, it also amplifies the reflected power, so 10D - 10R = 0 (still)...

1. The life of any speaker is a function of many variables including driver construction and amplifier construction and components for an active speaker like a subwoofer. I have 12+ year old subs that are doing just fine, some 20+ year old speakers that still meet spec, and some that have...

After going through three high-end AVR/AVP units in about five years, the last somewhat a nightmare, I purchased a JBL Synthesis SDP-75 (Trinnov 32) 24-channel unit my dealer was able to get for me at a "good" (but still very expensive) price. Their support and upgrades should make this the last...

I did not say that. However, I do not trust my ears without reservation, either. And I am an engineer, so my science is applied, not just theoretical. Differences are readily measured, less readily heard, but certainly possible. IMO/IME.

Sorry, I meant to quote the OP, was not responding to your post. I usually have little interest in other listener's comparisons; too often too biased and all that jazz. And I am certainly in no position to afford a $90k DAC. As I said if he -- or you -- feel R2R sounds best then by all means go...

I am not sure what you mean by "build". I have "built" DACs in the sense that I designed DAC ICs (mostly, not many discrete designs) at the transistor level (albeit mostly well above audio frequencies). I am guessing you mean to buy the interface and DAC chips, and perhaps design and build your...

If all you want is to manage the subs, you could try an Anti-Mode: http://www.dspeaker.com/en/products/anti-mode-8033.shtml They also have full-range models: http://www.dspeaker.com/en/products.shtml HTH - Don

IME (as a designer though not of audio amps in a while now) the biggest factor in amplifier performance changes with temperature (warm-up) are due to changes in bias levels inside the amp. That changes the gain, distortion, noise, output impedance (damping factor), and many other things. This...

I'm with @thrillcat : HDR was a step up in picture quality and the real draw to a 4K setup versus the resolution. Did have to fiddle with some settings in my Oppo and AVP to make sure everything played nicely.

I looked at the MX-890/990 a while back but you need a dealer to program it for you... From their website: "Professional programming by authorized URC Complete Control® dealer required". They do not have a list of dealers last time I looked; you have to fill out a contact form so their dealer...

What alternatives are available for universal remotes?

Been following Ethan for many years, thanks for bringing him here!

@Sonnie : I cannot imagine anyone is going to complain about a small difference. As for power, where P = power, I = current, V = voltage, and R = resistance, you can calculate the dissipation per resistor with a little bit of Ohm's Law. V = I * R, V / I = R, V / R = I P = V*I = V^2 / R = I^2 *...
