Recently, Will Vincent built for me a set of "Super Baldwin" mono amps based on the 6l6 output tube. 25 to 30W per channel based on output tubes used. I use these amps into the new Falcon acoustics LS/3/5A BBC monitors. Similar, I believe to the P3sr speaker by Harbeth. Incredible match-in the near field. I do what red wine does when listening, felt with a 2-way. Point-check out Will Vincent tube amps-incredible build quality, sound quality, reliability, plus-no SS amp will ever sound as satisfying as a tube amp.
