Simply, buy the dearest! With Arcam, it's always worth getting the top models. I've owned Alpha 8, Alpha 9, and have extensive experience of CD23t. Each is better, significantly, than the one before. Bear in mind that the older Cd92 has the dCS ring dac in it, a very special component; the latest Cd192 has Wolfsons (4 per channel!) instead. Leave the 73 out of it and compare these two, in yr. own system. If you have to buy without audition, go for the newer 192; it's a cut-down FMJ 33, a player highly regarded everywhere (see Stereophile July 2004). But you must audition at home if at all possible. Matching is everything.
Arcam decision
I really need to upgrade my cd player. I have the choice of several Arcam models. One is the CD73@ $700, another is a used cd93 @ $1200 and the last and most costly is the cd192 @$1600. I am stepping up from an older pioneer elite from 1996 so I know all will be a major improvement. I have a rotel amp and B&K pre w/ Snell type D's. I defer to those in the know for assistance with this decision. Thanks.
