Just hooked it up and getting things warmed up and the juices flowing. I will not comment on sound for a few days, however I Will say:
Extremely SOLID build quality, very heavy and substancial....looks beautiful and again Heavy for a preamp. Bigger than I thought from photos, silver faceplate and blue light matches my HCA-2 very nicely.
Initial sound is very very good,,,,,.....no I will wait til it gets a little more time on it. This is a LOT of Pre for $650.!!!
