Have you tried it? From what I have read its generally accepted that the other way around works better to get the best of both worlds.
No, it was what I experienced, not a generalisation and therefore also not utter bollox. 
That's taking it out of context a bit, a guitar amp is supposed to distort!
Well if it wasn't harmonic distortion it was something! I really don't think I was driving the amp too hard. The main experience I am thinking of was with a Cayin A-88T.
SanJ, the general opinion here seems to be that you should go all valve or all transistor... but I really feel this is misguiding you so do have a listen for yourself.
