Ideal and affordable are two different things. Cosmetically, a used
earlier Mac CD player would be good, I would call and find out what the
earliest players Mac FULLY SUPPORTS (has all parts for) are, and buy
one of those.

Any of the modestly priced universal players are good choices because
doing any better is going to require an outboard DAC in my opinion. In
fact , some really cheap players are actually good sounding, of course
they are throwaways as far as repair goes.
