I heard an earlier version of the Wolcott at a dealer in southern Cailfornia who was auditioning them as a possible addition to his line. Though quite good, the "breakthrough" Wolcotts were no match for 3 top tier "conventional" tube amps, one close in price. I understand that the amp has been, and in fact, is still, being revised. The dealer chose not to take the work-in-progress on. They are certainly promising. Time will tell.
