It makes absolutely zero difference. You could raise the calibration levels of all the speakers by 5dB and then your equal playback volume would be 5 dB lower, but it wouldn't make any difference except that the playback volume would be 5dB lower. It's not like you're losing power or anything. People tend to confuse volume levels with power. They have no relation to each other. I'd just leave it how it is, though you can make adjustments to some individual levels to increase or decrease them for personal preference, like you've done. You might want dialog a little louder, so you turn up the center channel, for example.Maybe you can give me some insight here audyssey seemed to turn all the channels down to let's say -2 or -3 except the right rear surround was -6.5. wouldn't it make more sense to work at 0 ? What I am saying is most of the channels we about --6 and -7... So why not leave those just at 0? Seems like it's really going backwards with the levels..I have to turn the volume up to 50 for normal listening volume..seems about overboard
