Ever since I got my H/K AVR635 a couple weeks ago I'm starting to see the light... I notice that out of all the listening modes and DSP settings, my cd's sound the best with plain old 2 ch Stereo! Sub turned off. The music just sounds cleaner. I didn't notice this dramatic difference with my Onkyo 503.
I've never enjoyed my system this much. I can only imagine what would happen if I introduced a fatty amp into this mix.:D I hope I can fight off upgrade-itus long enough to pay off my debts from the last couple upgrades. :p
