Personal Preamp Evolution.

Used a KenWood KA-6100 integrated as a pre after a little snip-snip, solder-solder. If I knew than what Iknow now, I'd have installed pre-out RCAs and done the same for main in.
Replaced that with a NAD1700 about '86 or so, than junked that out for a nice integrated, a PSAudio GCC250.
I don't change equipment that often, to have a 'history'.
