Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: With that sort of efficiency you'll want 30 watts at least.

At higher power levels SETs make higher ordered harmonics which show up on the transients, causing them to sound 'dynamic'. But this is because the ear uses the higher ordered harmonics to sense sound pressure, so this is distortion masquerading as 'dynamics'.

One thing about how the ear perceives the higher ordered harmonics- it also converts them to a tonality. This is heard as additional brightness and harshness and its why so many solid state amps are bright. The thing is, because the higher orders are also used to sense sound pressure, if they are present in sufficient quantity, the system will sound 'loud'. If they are not present, you won't be able to tell how loud the system is and it will sound more relaxed. IMO the higher ordered harmonics are the most insidious of all the colorations.
