can you hear phase shift at high frequencies ( or any frequencies at all)?
the wavelength of 10k is about an inch. if your ear is about 1/2 inch
closer to one speaker than the other ear is to the other speaker, then
there will be a relative phase shift of 180 degrees. besides, if your
head is much bigger than 1/2 inch, i dont think you can hear the
difference anyway. but some people are amazing and can hear amazing
things. 
cd are very good, and the sound nice, but their main advantage is
not that they sound nice. the main advantage is convienience. they do not
need to be rewound as tapes do. they are smaller than records, and
most cheep record players can not repeat or skip around without
my using my hand to move the needle.
