Well, I haven't tested max db yet, but I know that at higher volumes, the sound seems a little strained, especially higher frequencies. I would like to get that volume without, I guess, straining the amp or nearing its max. I don't think it's the speakers to blame for what sounds like distortion.

To get reference levels of 76 db band limited pink noise using DVE, I have to turn it to +7.

So, I'm a little vague on the pre-outs. How would I connect another amp if I wanted to for 2 channel without affecting the settings for multi-channel?
