  If I had meant audiophiles I would have stated such.
The "tweaks"
 are the ones that can hear the nuances in an amplifier that cannot
 be quantified because they don't exist. They describe an amplifier
 as if it were a bottle of wine... Somehow they are never willing to
 submit to a double-blind test to check their palette. 
Although this is way off-topic, I think that a lot of the "tube sound" claims
may have to do with audio distortion.  Here are some audio tests of a type of tube amp I
built:

I saw these tests before building the amp.  And since I have a significant hearing loss in
both ears, I built the amp just to play with tubes, not for any audiophile reasons.  If
the people who can actually hear any difference claim to like tube amps over solid-state
even if that difference is actually due to audio distortion, more power to them.

On the topic of imagining audio differences that aren't actually there, I read the
article referenced here way back in 1983.  I was not surprised by the results:
