I am a bit puzzled by some of the comments I've read on the net.
Some (not all) of these puzzles are summarized and listed below.

> "...distortion specs on CD players are far better than the
> ear has the ability to detect..."

> "...people could not hear distortion that was artificially
> introduced until it reached a level of about 0.5%..."

> "...the ear cannot hear phase differences above 10KHz..."

> "...digital is emphatically superior to analog..."

If all of these statements are true, and since the specs between
digital players are too insignificant for the ear to detect
(0.05% THD, etc.), then why does a Sony CD player sound different
from a Luxman CD player (or a Hitachi, or a Technics, etc.)?
