p.s, so with no digital in your system, how do you address all the bass mode peaks and dips etc in your room? You don't mind hearing them?
Jim Smith addressed them as best he could, first through measurements, then by listening to carefully locate the listening seat position and then speaker positions. The room is not perfect, but by the time he left, the sound was pretty darn good.
The funny thing is that I sometimes attend small ensemble performances in actual chamber settings. A couple of years ago, I changed seats during the break between movements. I distinctly remember hearing a bass node peak during the solo cello. No, I did not really mind hearing that. I quickly noticed it, mentioned it to my friend, and enjoyed the rest of the performance. After all, it was a real performance of acoustic instruments in a real space, the way the instruments were originally meant to be heard. I certainly would not have wanted that performance mic'd, amplified, and then altered digitally to rid the room of bass mode peaks and dips.
