Thanks Bob. It was one of the most fun articles to write since it is a topic not covered elsewhere.
BTW, you will definitely like the next one: it is a "deep dive" into the audio performance of AVRs/Processors in general, and HDMI in the specific. It has even more data and measurements than this one.
Here is a shot of my test bench to wet your appetite:
---- I recognize all the components from that picture.
And yes, I would be extremely interested to read this one as well.

BTW Amir, back in 2009, I believe, I started a thread over at AVS Forum;
on all the best Automatic (and Manual) Room Calibration and EQ systems.
Few smart members noticed it, and a bunch of other members were waiting to have the 'experts' or members/owners with vast experience sharing their knowledge in one or more of these systems.
Unfortunately it went nowhere.
Yes, I'm like Kal Rubinson (and others) on those things; the future improvement in our listening rooms, from multichannel surround sound (music and movies) & also high fidelity stereo sound.

* Here at WBF, I thought of restarting it, from all what I know already on some of the very best systems (ARC, Audyssey MultEQ XT Pro, Room Perfect, YPAO, Advanced MCACC, Trinnov, TacT, SARS, REW, and others like JBL Synthesis, and more...), but I think the interest from the overall average's membership here is not up to it. ...Or at least from all these systems in only one thread.
Furthermore, in another audio forum, which I won't name, I tried to have all the pertinent information contained in one thread only; sort of a reference mega thread.
But there too I failed; most members from that forum were not taking me seriously, or they simply didn't want to expand their knowledge.
I've learned a few things over the years .... And I had to adapt with the mentality of each venue with their people (audio/video forums and their members).
It's not easy to go where you would love to go, and learn more from the pros. ...All in one thread only, from this very specific subject. It is just too complex as each system is quite different from the next.
Still though, it is nice to compare them all from one place; Parametric EQs, Graphic EQs, digital DSPs, FIR filters, IIR filters, Frequency, Time domain, Phase accuracy, 3D Remapping, Vertical & Horizontal sound planes, DSX with Width and Height channels, Dolby Atmos, 9.2-ch., 11.3-ch., etc., etc., etc.
...Computer Optimization .... in sound. ...That's the future that we live in now.
