Nerd Lab?!

As an electrical engineer myself, I'm insulted. Nerd Cave or Nerd Command Center are preferrable.

Serious now:
I've noticed the L-R volume difference in the pink noise on my 970. I haven't noticed this using the pink noise source on my bluray player which is what I used to do the final channel setup. I'll have to play with this more to quantify the effects.

BTW I haven't found a home theater setup disk I really like. I've tried the DVE and Avia disks and they were nice but neither allowed me to really tweak in the audio (especially the home built sub) the way I wanted.
