Jim,
You are conflating two technologies here, digital crossover and convolution engine.
Dave was using DEQX as a digital crossover and if I am correct, you helped Tom setup the convolution engine for room correction.
Room correction obviously makes music more enjoyable.
But the point we are discussing is the noise and/or jitter levels I perceived at Daves place. That cannot be eliminated with or without room correction.
Found this DEQX promotional video on YouTube. It talks about timing correction.

Not quite correct. The work done by the DEQX technician was a very complete adjustment of the system including physical placement of the speakers in the room, timing issues, crossover points and slopes, level setting, and EQ. Jim and I were essentially spectators and moved the speakers and microphone around during the process. It took 4 1/2 hours. As Jim said, this is a complicated process. The installation manual for the DEQX is 143 pages long. Even if I knew "every button to push", it is not a substitute for the experience that the technician has amassed doing this on a regular basis on countless systems. The microphone does not have HRTF and the computer does not have psychoacoustic capabilities. I decided to pay the $400 to get it done right. Yes, I have done lots of little adjustments using the DEQX but for the major setup, the experience of their people can't be beat.
It is also interesting to see in the link that you supplied that even the God of analog, Michael Fremer said there was nothing digital sounding about the DEQX. Again everyone has their own preferences, but I will say again, any technology, WHEN PROPERLY EXECUTED, can give good results. You have to do what works for you but the key to success is really knowing what you like, knowing what has to be done to achieve that and then doing it properly.
