The DSP modes are kinda gimmicky. I think I played around with them once on my first Sony receiver. That was about seven years ago.

Wait, I take that back. I have a Logic 7 setting on my H/K that I tried when I first got it. My speakers were all different and I got mixed results. Nice full sound, though.
