Ray-

Thanks. I also used Avia and an SPL meter to do this on top of the Auto function w/Yamaha. I found that they yielded "similar results". I manually changed the Center and upped it by 2db's. The most complicated thing is the Sub on the Radio shack sent it off the chart!! I used 75 db's to calibrate, and simply upped the center for my own taste (do lots do that?) and upped the Sub by 5 db's as that seemed like smoother bass. So it looks like I'm on the right track eh?
