The result was my T39 'The Tradition' Mk VI, for short the KISS 300B
'Ultrafi'. Does it measure as well as the blameless 6SN76SN7300B? No,
it doesn't. It can't because I deliberately sacrificed some of the
precision for greater warmth. Does it sound better? Depends who you are
and what you expect. Americans previously accustomed to the
banksa6550/NFB paradigm may well prefer the drier 6SN76SN7300B. I
think the KISS Ultrafi sounds better but then I like slightly warm
amps. Japanese audiophiles who like what they call 'British sound' may
well consider it rather on the precise side of the tropic and wonder if
I have detuned it enough.

And there we have it, from the horse's ass.

KISS 300B is *not* an 'ultrafi' amp at all, it's just a cut-down
standard 300B amp with *added* 2nd harmonic distortion to give it an
exaggerated amount of typical SET nonlinearity. What a crock!
