Especially when we have solid COLBALT out put trans in the mix,:) or you could dispense with the output transformer altogether.
These powerful trans, are not cheap, I should add.
My speakers are 97.5dB, 16 ohms and flat to 20Hz. I've yet to hear an SET on that system that can make proper bass. I've got LPs I produced so I know how they are supposed to sound- I was there when they were recorded.
The thing is, SETs can be better than some PP amps but generalizations like saying they are 'better than all' usually don't work out. At the very least its like 'the fastest gun in the West', taken down eventually by the guy that was actually faster.
