The original. Carver C1 Sonic Holography Preamp. I had one of these when they were new. The first time I heard the guy at my local shop push that button, I have been a hifi nut since.
This Preamp is in great shape. I have cleaned the switches and it makes no noise. I do not have the original box, but have boxes that will ship it safely.
It you are looking for a nice sounding preamp with an interesting feature, this might be the one.
