I have had mine since last December. I needed a 0 gain pre-amp to run with my high gain Yamamoto A-09S 300B amp to a pair of Zu Definition Mk II speakers. While this may sound like a somewhat unnatural pairing, I have been extremely pleased. As Tvad indicated, quiet, resolution and dynamics are all there. In addition I have found it to be very balanced. While this is my first high dollar pre-amp, I have owned the Blue Circle BC-3, Joule Electra LA-150 Mk I and First Sound Presence Deluxe Mk II. I have also had in my system pre-amps from CAT and Supratek. While none of them sounded bad, they all left me with a feeling that something was missing. That feeling is now gone. I never think about the pre-amp anymore. That's probably the highest compliment I can give.
