Solid State vs. Tubes - What if Transistors came first?

lous- I wonder how VAC manages to get 100 watts from a pair of KT88s in their 200iq amp without prematurely blowing them up in Class A/B configuration.  They tightly regulate the tube bias and have oversized/massive transformers of high quality.  Are you able to figure it out?  Their amps never sound undersized or hazy.

It's odd.  I always felt it's the solid state that has a bit of a haze while tubes have better transparency.  Maybe some have attributed this "haze" as being laid back and having less of treble present.  I always felt that solid state a lot of time is guilty of having the treble being a bit hot therefore having an artificial clarity.

andy2 - Possibly, but as a drummer I appreciate crystal clarity up top for cymbals etc...  Also, the excitement and tension between the notes is a big thing for me, and a very quiet noise floor is required.  Ideally I should have 2 systems I guess?  Anyway, it’s all fun and sometimes mood dependent.  As for the Haze, BAD SS could have some as well I guess, but not with well designed stuff.  FYI, I am a big proponent of balanced signal paths, which in my experience sounds so much more Live than single ended.  I want nothing between me and the source sonically.  The gestalt should be that Only air separates me from the musicians.  Sometimes that may be too much for some listeners.

Wikipedia has this to say about KT88s and their wattage;
"A KT88 push-pull pair in class AB1 fixed bias is capable of 100 watts of output with 2.5% total harmonic distortion or up to about 50W at low distortion in hi-fi applications."
Just because a tube distorts less obviously doesn't mean it's clean. That said, as I understand it you can get a clean 60 watts out of them. I only worked with tubes in video and announcing systems, I have never worked in tube amplification design, so my knowledge is finite. That's why I went to Don Sachs and Roy Mottram, I have learned a little bit more about them, but I am far from an expert.

Andy2, I don't know what current SS amplifiers are using, but older amps used standard rectifiers, most never used snubber circuits to deal with the fact that diodes ring. Replacing them with soft recovery rectifiers like IXYS bridge rectifiers clears up a lot of strange issues with midrange and high frequency noise.
