All Amps Sound the Same....

Mrtennis, you are welcome. In answer to your question: Yes, I believe that
all music evokes an emotional response; anything that can fairly be called
music. It may not be a positive or pleasant response, but a response
nonetheless. Earlier you wrote that there is music of the brain, cerebral in
nature, and that does not necessarily evoke an emotional response. You
cited TWC as an example. Later you write:

***people are different in their reactions to music. i find the well tempered
clavier very helpful when solving mathematical problems.***

What is it then that causes this "help", if not an emotional
response?

BTW, a common discussion among musicians and musicologists is the
notion (by now, fairly well debunked) that Bach's music, particularly
TWC, is to be performed in a cold, mechanical (mathematical) fashion.
Not so. Additionally, it is also an accepted idea that in Bach's time a
tempo marking was an indication of the intended emotional character of
the music ("Allegro").

Perhaps the well tempered clavier stimulates the left side of your brain, without necessarily introducing any conscious perception of an "emotional" response?

A perfect cappucino in your favorite cafe might evoke an emotional response, but caffeine by itself is only a stimulant?

What other composers or music, please, would you recommend to enhance concentration and/or to prove that all amps do not sound the same.

I feel that Mrtennis invokes instigated contrast to fuel his narcissist mentality.
He can’t help it of course, but we all can.

in addition to bach, i would include purcell, scarlatti,froeberger, and other composers who wrote harpsichord music during the baroque period as very helpful when thinking is the sole activity.

Kijanki, a well crafted telling of the standard audiophile dogma with just a hint of hyperbole. But is it possible that it's not large amounts of negative feedback that's the problem, but instead the careless or sloppy use of NFB in circuits not optimized for large amounts of NFB? You should read up on the design criteria for Soulution amps/preamps. Their products feature massive use of negative feedback, outrageously good measurements and supposedly outstanding sound quality. I think you need to rethink your opinion about NFB.

Leaving the world of NFB behind, my earlier point was to point out that science (measurements) is best used in the design of electronic equipment intended to reproduce music and emotions are best employed when listening to music. I think the audiophile world is on the verge of what might be a significant advance in sound reproduction quality as engineers are becoming more knowledgeable about what to measure and how the interpret the data.

One last point, Rowland amps, even the ICE-based ones, measure quite well. Come on down from them hills!
