What piece(s) of gear did you sell/give away that you would like to have back?

Precision Fidelity C7 tube phono stage. Designed by Bruce Moore (MFA and Paragon). Advanced cascode circuit design using 12AX7's. A pair of potentiometers and a selector switch on the front so it can be connected directly to an amp. Bought it new for $500 from American Audiophile on 61st and Madison, NYC in '79. Stupidly sold it a few years later for half-price for some fast cash!

My first pair of Quad 57's, which I had in use from '81 to 2000 - 19 years! Again a stupid sale when I needed some fast cash!

I bet the introduction of CDs in the early 80s had some influence on your decision to sell the Precision Fidelity phonostage, roberjerman? That sounds like it was a very nice unit. $500 seems like a pittance these days, but it was big money in 1979.
