For your reading pleasure.
"Articles last month revealed that musician Neil Young and Apple's Steve Jobs
discussed offering digital music downloads of 'uncompromised studio quality'.
Much of the press and user commentary was particularly enthusiastic about the
prospect of uncompressed 24 bit 192kHz downloads. 24/192 featured prominently in
my own conversations with Mr. Young's group several months ago.
"Unfortunately, there is no point to distributing music in 24-bit/192kHz format.
Its playback fidelity is slightly inferior to 16/44.1 or 16/48, and it takes up
6 times the space.
"There are a few real problems with the audio quality and 'experience' of
digitally distributed music today. 24/192 solves none of them. While everyone
fixates on 24/192 as a magic bullet, we're not going to see any actual improvement."

"192kHz digital music files offer no benefits. They're not quite neutral either;
practical fidelity is slightly worse. The ultrasonics are a liability during
playback.
"Neither audio transducers nor power amplifiers are free of distortion, and
distortion tends to increase rapidly at the lowest and highest frequencies. If
the same transducer reproduces ultrasonics along with audible content, any
nonlinearity will shift some of the ultrasonic content down into the audible
range as an uncontrolled spray of intermodulation distortion products covering
the entire audible spectrum. Nonlinearity in a power amplifier will produce the
same effect. The effect is very slight, but listening tests have confirmed that
both effects can be audible."
Here's the rest of the lengthy article.
