I guess thats why he excluded Pentodes, and looking at the list of
valves, indirectly heated triodes, or were you choosing to ignore
that ?


By doing so he excluded an apples-to-apples comparison. Comparing a
transitor to a triode is not an apples-to-apples comparison because the
transistor has so much greater amplification. If you apply enough local
feedback to a transistor amplifier to make it comparable to a triode, it's
often even more linear.

Yes, agreed, gain is cheap with transistors, but you are still assuming
that feedback is without its cost in sonic terms. And before you go off
on one of your rants, a zero (global) feedback SET does some things that
no other type of amp does. Yes, it has faults, thats why I don't at
the moment have one, and yes, to get it anywhere near usable you are
talking about a high cost if only for the iron. BUT, sit someone down
infront of a well designed SET, and a high enough sensitivity speaker
and it will communicate to them is a way that nothing else can.

And no, you can't sample that sound and push it through a comparitor.
