Which high power SET

I have heard the Wavac. I have also heard some other amps recommended in this thread. What is important to note is, SET or PP, the output tubes have a major contribution to the sonic signature. Most of the big tubes, especially 845, 805 etc have a certain "artificially big sound" about them. They lack the musical subtlety compared to the smaller tubes. This is true even with the bigger Wavac. You hear all the details and of course have lots of power but the sound is more mechanical. It is more "sound" vs music. In that regards I discovered that even a well designed Push pull amp sounded way more musically satisfying if the output tubes are one of the smaller tubes (2A3, 45, 300B, EL34, EL84, Kt88, 6L6GC, 6c33c etc). I have not heard a well implemented 211 tube based amp so I cannot comment on that. But 845 and 805, not for me.

I suggest you also look at Unison Research Performance amp. It is more like a high powered SET without using big transmitter tubes.

Hi Charles and Jeff, I have not heard the Absolare. My comment was more general. Just like a 300B, an 845 also has its own signature. In fact companies like Line Magnetic audio have amps where they use 845 output tubes driven by 300B as driver tubes just to compensate for the that certain lack of delicacy. But even with those kind of designs I could not accept the 845 way of presenting music. If I get to hear the Absolare, I will definitely post my thoughts in some or the other thread, thats a promise :-)

For me, #1 priority is amp's ability to drive speaker sufficiently. If not, SQ will suffer whether low or high listening levels from my experience.

Could not agree more.
