I have been fascinated by the idea of music servers but
unwilling to pay the price. Then it occurred to me I
already had the nucleus of a music server in iTunes on
my MacBook Pro. Adding a DroboS backup system gave me
all the space I needed and an Apple TV, with its optical
output, provided the way to pass the music to my DAC.

Folks have said that music played from an HD is superior
to all but the most expensive CD players. Let me say it
isn't subtle.

In terms of signal purity, hard drives are practically
speaking far more
accurate than CD players. CD discs can and often will
develop uncorrectable
data errors that are only partially concealed during the
normal playback
process. Their number may be low or even vanishing,
depending on the disc
and the player.

Is that so?

Yes.

explain to me how I can copy a CD with 1 hour
music in 2 minutes,
( on a 20 Euro CD player/burner ) do a bit compare and
find both the CD and the copy to be equal.


Every competent CD copy program I am aware of monitors the DVD drive for
uncorrected errors and retries any failed read operation(s). A standard
audio CD player does not do this.

Secondly, I said "Their number (number of uncorrected errors) may be low or
even vanishing, depending on the disc and the player.

I don't discount the possibility that you have been copying discs in such
good shape that the number of uncorrected read errors was indeed
"vanishing". I allowed for the possibility of a *vanishing number of
errors*, which is just another way of saying "No errors at all during the
processing of one or more discs".
