To answer some questions:
The way I tweaked the sub was to set the crossover frequency at 100 mhz (under the speaker setup menu). Any higher than that and the sound quality dropped. I don't know if this means I'm no longer running under the Audyssey setting, but the sound is still incredible. I tested it with various scenes from Revenge of the Sith and got the floor to shake a little
Yes, the volume is displayed onscreen. I initially had some problems getting it to display, but was able to get it to show up by accessing the menus from the receiver itself (the remote can call up the OSD now, but only after I initially got it to show up). Try pressing the setup button on the remote.
I'm glad to hear the flashing is normal...I was worried for a minute there
It's a bummer to hear Crutchfield's out, but from what I've experienced so far with this receiver, it's well worth the wait. Having seen how easy it was to do the auto setup and eq (even though I had to switch the wiring on my speakers a few times before it stopped saying they were out of phase), I'm blown away by the improvement in sound.
