djjd really provided a lot of good info. He mentioned the Sonic Frontiers Line 2 and 3 preamps (which are Class A). The Sonic Frontiers Line 1 also includes the SSP, is a lot less money (Which is Class B), and with high grade 7308's in the first position are really close to Class A. Just a little more info for your quest.
2 Channel Pass Through for Home Theater
I would like to upgrade my 2 channel listening in my home theater room. Is there a way to hook up a class A audiophile preamp and processor to my home theater system so that I can get better sound when playing CDs? Any recommendations on Pre-amps and processors that are truly amazing. (I like tubes) How about the Audio Research Ref 1 or 2 with a DCS processor? Any help would be appreciated. Some of my current components: Proceed AVP processor Proceed PMDT transport 6 Bel (Brown Electronic Labs) Amps Audio Physic speaker system all around (Virgos, Celcius center and luna Subwoofer)
