Re:double-blind, controlled test, please? (Score 1)

I'm told that due to the joys of the analog electronics, the actual frequencies from a cd range up to 11, not 22 kHz (because the system takes for samples, not two). Therefore, there is a real benefit to the new-wave audio standards that are appearing - as the parent mentioned, most people can hear up to about 20kHz, so we're getting an extra 9kHz for our money's worth.
