Do you really believe that, Dave?


It's a fact. Or is it that John Atkisnon is publishing lies about the
measured perforamnce of the SETs his ragazine reviews?


I thought you were in
the recording business. Surely you know that now amp
whatsoever merely processes the signal blamelessly. Those
with negative feedback, for instance, add artifacts to
the music, higher order harmonics.


Darn that John Atkinson! Why is it that the SET amps he reviews have far
more high order harmonics than a good SS amp with loop feedback?

For example:

I think you are fully aware Stuart that a amp built around a 833 is far
from a average example of a SET.

There's a Stuart in this thread?

OTOH, are you not aware that SETs have just as much odd-order
distortion as PP amps, it's just that the vastly higher even-order
distortion isn't cancelled out?
