In response to the waves made about square wave testing (pun intentional):
To Dick Grantges:
Thanx for reminding me that most square wave testing is done at 1KHz.  However,
when checking the treble response of a system, I would think that a 10KHz or
so test signal might be more appropriate.
I'll agree that the square wave tests of most CD players are better than those
of many analog transducers (e.g. phono cartridges and speakers) and further
that they are useful in determining the performance of filters on CD players.
I don't think that CD's are per se bad, far from it --- however, I am disturbed
that a relatively low sampling rate was chosen.
As for recommendations on CD players, if I were in the market right now, I'd
get the Kyocera DA-01 for two reasons: the phase response of its filters
and its error-correction performance.  (However, keep in mind that I'm not
that interested in fancy programming features - to me sound quality is the
crucial parameter.)
