The salesman claimed the speakers (hooked up to a Boulder amplifier that was most likely brought in with a forklift) reproduce music exactly as it was recorded
That's possibly not true and I'd even say
likely not true. And "revealing" may not be a synonym for "accurate".
I've never been in a real recording/mixing/mastering studio but
I'd expect the recording to sound darn good! ...Maybe not some modern over-compressed pop or rock, but a good recording that I like (like
Money) should sound awesome!
but is music intended to be reproduced exactly as recorded?
Well.... yes, or "as produced".
The goal of "high fidelity" is to accurately reproduce the performance or the recording. With certain classical or acoustic recordings reproducing the performance is the ideal but with modern studio recordings there isn't necessarily a "performance".
On the other hand, not everybody wants perfect accuracy. Music is for your enjoyment and some people like to boost the bass, etc. Personally, I like to use one of the Dolby soundfield settings for some reverb in the rear channels. I
think most people prefer a little more "room sound" than you get in a "dead" recording studio.
It would be silly to spend an obscene amount of money on speakers if you don't enjoy the sound. And If I had an unlimited budget I can't imagine spending that kind of money on speakers.
