I am in the final stages of making a preamp purchase to seperate a 2 channel system from my HT system with a preamp. I would really appreciate some feedback on the following SS units: Blue Circle CS (not the intergrated), Adcom GFP 750, Marsh P2000, Rotel RC 1090 and maybe your suggestions. I have a line on a BC 21.1 tube preamp if I decide for sure to go with tubes. My budget for SS preamp is up to $1500. Thanks to all in advance.
