The reduced high frequency phase shift would have >been well worth it. 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.
