Looking to get a stereo preamp, I have for sources a MH 7.1 turntable running through a Vincent PHO8 phono amp and then into a NAD AV 163 preamp. I also have a Oppo 105D universal player running into the NAD. The Amp I have is a Musical Fidelity A3.2cr. I want a stereo preamp to have the bypass so I can keep my NAD for surround capabilities. Anyone have suggestions, I really like the Sim audio Moon products but out of my budget. I want to stay at around $3500
