Saw Bob's post on another thread and thought "you've been talking to my mate" followed by "you're gonna be in sh1t for saying it like that"

So - to move the topic to a thread of its own where it belongs, be rude about valve amplifiers here.

I would start by noting that my mate, the arch-objectivist, Mr measurement himself, and all solid state, would concede that there is more to life than measurement. Indeed - one of the reasons I have got him interested in a hifi design again is because he is fed up with designing professional equipment where measurements are all that matters.

And he commented that Quad you loved was no way to design an amp by starting with class B and all its distortions, and then correcting it.

Just a quickie to get us going
