Hi all, got my 990 on saturday, going to see how I like it vs the yamaha 2500, set it up on sunday after work and played with it a bit{wife was home so couldn't open it up]well today I have been trying to calibrate the channels, what should the volume control be on? I have it at -22 but It sounds a little muddy and the sub volume seems low ,haven't used the auto set-up all manual,have speakers all, set to small sub on fronts crossover at 60, center at 80, and all surrounds at 100, it just doesn't sound right to me, I was using the 2500 with the icbm, do you think I should hook that up, am I doing something wrong ? I want to give it a fair chance vs the yammy 2500 thanks
