I think this was the metho used by Bob carver in his Stereophile
challenge where he claimed he could make his amplifier sound just like
a much more expensie tube amp.

Which he did, judging by Stereophile's golden ears of the time,
IIRC.

Yes they did concede that. Unfortnately he could not maintain the same
levels of likeness in his production model based on the challenge. that
was not only the conclusion of the Stereophile review of that
production amp but a concession made by Bob Carver himself.

No, that's not right. Carver conceded Holt could tell the
difference (although IIRC Holt thought Carver's amp was the tubed
amp during the test), but Carver claimed that the original tube
amp had changed in the intervening time. Not an implausible
assertion given the nature of tubes. And I think the original
Carver-tweaked solid state amp - the one Holt and his
golden-eared pals couldn't distinguish from the tube amp - had
been lost or left behind or something ... bad science there.

Bt in a
world where all amps sound the same what could any of this mean?

I don't think anyone has claimed all tube amps sound like all
solid state amps. Do you have a reference for such a claim?

yeah, the test was done blind. hmmmmmm.

Well I think both tests were blind, so what is your point?
