Just bought a used B&K 307 receiver from an original owner, have JM Lab Cobalt-S, Center, fronts, and Surround 800's + SW800. Music, Stereo, Surround (digital cable in DTS!!!), everything sounds like it should, and better than I expected. But, with both Kill Bill's played back to back, there was hardly a peep coming out of the rears. I played around all throughout the movies, THX, Surround mode 5-6-&7, and never got an audible signal from the rears, and the center sounds like a blanket's in front of it. I must be doing something wrong, or the DVD's not doing the job. So far I'm delighted. Anyone know why my 4 y/o Sony DVD sounds like shit, while my digital cable sounds phenom? The rears really sing with the center and fronts, but there is virtually (almost) no sound from the rears during DVD play. Is it because I'm using the Fiber cable for audio? Or is my DVD player too old to process signals on this level of quality? My dad says maybe it's the movie, but it was Kill Bill II for god's sake! That should have the ultimate sound. The Center sounds so muffled and cluttered, it's almost inaudible speach! But again, cable TV and CD's played in surround (pro-logic) sound divine. I don't even want to play it loud it's so clear! At 32, a first in my life. I know I have some educating myself when it comes to a receiver on this level of quality, but I don't know where to start!
