Hi Chris,
I run an Onkyo 707 with Elac CL-142 (fronts), Elac Dipole 60/4 (surround), Elac CC241 (center) and a Velodyne SPL-1000 (sub). I upgraded to 707 from a 674 and ever since I upgraded, the quality of "voice" is terrible. If I reset the system and don't run Audyssey, the voice is much better, but the overall experience is terrible. So I'm forced to use Audyssey calibration. I have tried various setups and nothing seems to work. So far the best I got was setting the amp to "normal" (the other being bi-amp). The impedance set to 4 ohms (all my speakers are 4 ohms rated).
With my old 674 (it had 2 EQ) the voice quality was awesome. I can't believe that 707 can be that underpowered compared to a old 674.
I have followed all the setup guidelines from this site and others as well. But only with the guidelines from here gave me that setup I was ok with.
Additionally when I setup the crossover to 80hz (THX mode) like you had mentioned in your Bass Management blog, there is an omnipresent boom in the background constantly. I have turned down the sub volume to a bit less than 1/3. But I still sense a bit of vibration/murmur.
What could I do better to calibrate the system? Thanks for this beautiful technology. I still remember my old days with my Onkyo 777 setting up levels manually.
