Yeah, there is a big disjoint between what people claim they can hear and what they actually do, isnt there? And also between what they claim and what published specs say - my favorite is the guys who claim that one amp is warmer than another when both are 20-20k @ 0,1%. Yeah, good luck hearing that.
I have to admit, i do not know enough about the science of audio perception to say which measurement/spec corresponds to perception. I had rebuilt a Dynaco ST-70 with Ned @ Triode Electrics's mod, and it sounded fairly neutral and not at all lush/mid-heavy. With my 2A3, I did find it more lush - you are right, it could be the harmonics giving it that extra body. I never measured the FR.
I have a Systems Engineering degree, although i've never used it - so know just about enough to be dangerous to myself :). I do think that the audio world could do with the removal of a few naked emperors, though.
I think a lot of people can't describe what they hear and either misuse terms or use some of the popular nonsense terms. And then once in a while you read a description that makes sense and that is refreshing. IMO far too many repeat the "magic words" they hear in the forums and things begin to take on a life of its own.. The year is 2014 and the truth is that there's a great deal of excellent equipment available at very reasonable prices, some that are overpriced and maybe add some value due to styling and construction. There's also some big bucks stuff that if you ask me is made for the benefit of lab tests not human pleasure because they measure to values we cannot hear, but some folks must have it because of ......
Whatever happened to enjoying some music, sometimes I wonder.
I think that to find a tube amp that has great benefits without excessive noise or distortion means opening one's wallet a little more than for SS and looking carefully.
