I heard one of their preamps a my NY dealers. I am just not sure which one, but believe it was 20-25K, line stage only. It was very impressive, and this dealer has had some very formidable preamps, including VTL, and CAT, to name a few. I did not inquire much, only because I was concentrating on the tube amp that I was there to hear, and eventually purchased. This preamp is certainly worth consideration. I don't want to be a cheerleader for the dealer, but he is a great guy and has some serious equipment.
