Thanks for the response Ritz, yes I would be using the 3805 as a Pre/Pro only, one of the reasons I'm a little reluctant to buy another Amp is because it does perform so well. I figure about 107 Watts per Channel with 5 Channels driven so it's pretty good. However I'm working towards a System that's going to be around for a long time and I have a bit of Cash left after selling my Motorcylce so I'm trying to determine if the additional Amp (200 Watts per Channel x 5)would pay dividends in Sound Quality... a tough call so I'm try to research the heck out of this before I make a decision
