Here's an interesting and well-written article that should have the
AntiSEpTics foaming at one or more of their body orifices:

This bit is particularly interesting:
"Then there's the interesting issue of distortion products. SETs include
even- and odd-order distortion products in their outputs (as in nature, so
to speak), while push-pull circuits cancel out even-order distortion by
design, leaving only the less musical odd-order products intact. Now
look...there's something to this. It's suggested that the sound of
single-ended triodes has much to do with their delivery-intact-of the full
spectrum of distortion products. "More distortion is better?" I hear you
ask. Well, it's less humorous than it sounds. Might "unnatural" proportions
of odd-order distortion account for part of the sound of push-pull?
Something to think about."

... and should be read by those here who are continuing to confuse the
radically different terms 'realistic' and 'accurate'..


But I hope you didn't miss this bit:

"The Tweak Gallery was full. Three Shun Mook Mpingo discs on top of
each speaker, left at 7 o'clock, right side pointed to 5. I also
placed one Mpingo on the top cover of each amp in front of the
rectifier tube, where there was some open real estate. The balance of
the room treatments were as described in June's "A Matter of Taste"

Sums up the mood of the article quite nicely.
