Thank you for your excellent article on integrating Paradigm S2 v.3 speakers with Paradigm's top-of-the-line subwoofer. This was of particular interest to me as I am about to purchase two S2s, which I intend to integrate with my JL Audio Fathom f113 subwoofer.
I would suggest that you arrange to get a loaner Statement D2V from Anthem and run ARC on your setup. I am an electrical engineer, and before I tried ARC, I would make the same kinds of statements as you regarding speaker optimization using a room-correction program versus manual adjustment. What I found when I ran ARC was that while I was able to remove low-frequency room resonances as well as the ARC system, I could not produce anywhere near the precision and clarity in the frequency range existing for several octaves around the cutoff between my speakers and the Fathom. This difference was not insignificant, but rather took my existing system to a new level of performance. As an aside, I consider the Anthem D1 and its successor D2V the finest, most adaptable, and usable pieces of audio equipment that I have ever owned.
I am glad to see that someone else is extolling the virtues of audio-only linear PCM recordings made at 24-bit/96kHz and 192kHz. I have also purchased all of the Blu-ray 2L audio recordings and found that they are the highest-quality recordings that I have heard on any medium, be it CD, SACD, or vinyl.
Keep up the good work.
