Hello, my interest is in hi res audio mostly. I have a home theater system, but I really love my 2 channel audio system. I am looking to buy a pre amp at the moment. I have built speakers from Danny Richie's GR Research for my home theater system. They sound fantastic, and were a lot of fun to build. I had to buy Sapphire M-3 speakers for my 2 channel system for space reasons. They sound fantastic. I don't have to use sub woofers with them, because of the 15" woofers. I use separates on my 2 channel system. That's why I am looking for a preamp. Thanks, tedjen
