you should never, ever listen to what the layman considers to be true as far as ideal sound, without interpreting what he says based on your knowledge and experience.
People know what they like, but often don't know what they will continue to like.
it takes someone who knows the art to make the critical judgements of 'how much', proportion, loudness, eq etc.
most people's idea of ideal great sound is: loudness button pushed in, bass and treble almost to the max, 10 different speakers incl. tweeters, midrange, woofers, subwoofers etc. volume on the onset of distortion..
just like any other artform the people who have been through it and have studied the LONG-TERM effects of various compressions etc. can judge the right amount, the correct proportions etc.
What SONY can about this, and probably will do, is to build cd players with built-in mastering.
home multi-band compressors and eq's and tape emulators, and tube emulators etc. so that everyone at home can fuck up the signal as much as they like, and become 'experts'.
there is a HUGE difference between wrecking the audio at home and mastering it like a layman would.
