You assumes a 'standard' example, so I'll do the same:
It will also read at x1 speed. This can help reduce the chance of
individual read errors, so meaning less need for the strategies used by
'computer' drives which may re-read to combat such errors.
An argument can be made that a higher quality transport (more expensive)
may read disks without issuing as many errors. Are those errors audible?
Unlikely, except under extreme circumstances.
However if someone has hundreds of CDs some may be 'extreme' cases. I
certainly have some that won't play well in some machines, but work better
in others. So if someone only has one player it may be useful to buy a good
one.
I note, though, that "expensive" isn't a synonym for "good" in this regard.
:-)
Some expensive players use multiple DACs, whose outputs are summed,
allegedly in order to reduce errors.
Can also be used to help reduce the effects of intersample peaks requring
an output above 0dBFS. Given how many popular discs have this problem, that
may be useful.
Best sounding player I've had in my system?
A Marantz CD80 (ca. 190-ish). Fabulous sounding player. Not stupidly
expensive. Not cheap either.
The machines which I've found most likely to play a CD without problems are
actually the old Pioneer CDR-509 recorders. These have 'legato link' DACs
which dodge the above oversample problems. But since I'm happy to use an
external DAC I've preferred them feeding either an old Meridian 500 series
DAC or, more recently, a nice Benchmark DAC. (Mainly bought for USB use.)
The above said, I've found some discs that the Pioneers refuse to play
which some other Player then plays OK. So my general impression is that
seems a matter of which area a given player copes with best/worst.
