My Precision Fidelity C7 tube phono stage. Designed by Bruce Moore of Paragon 10 and 12 fame - later MFA (Moore, Franklin, Associates). The C7 had a source selector with four inputs and a volume pot so it could function as a passive preamp. I bought it new from American Audiophile in NYC in 1978. $520.
As you have moved on, are there any items you remember fondly...or most fondly?
As many on this site, I have had much in the way of the "high-end". There are, fortunately, many good items I could list that are still in my head/heart....but the two that come to mind quickly are the Thiel CS-1.5 and the Conrad Johnson ART pre-amp.......If I go back to the beginnings the DQ-10 would be one of the most impactful to my audio/hi-fi experience/knowledge. I don't really have the space right now, but when I do, I may put together a "retro" system for fun and nostalgia....you know, kind of like doing a '57 Chevy two door hardtop with a repaint, updated suspension/brakes and a 350 horse 327 with a Muncie 4-speed.....etc... Although a 288 GTO and tickets to a live performance in Copenhagen would be O.K. too.
