Listen to practically any CD player that interest you. Take some time to acquaint yourself with its sound. And then listen to the Audio Aero Capitole, just for the purposes of differentiation, as this player is certainly expensive. This will expose you to the chasm of sound differences between the various CD players. It did for me. I now own the Capitole. The differences were not subtle (listened to Naim, Linn, Rega Jupiter, Cary, Levinson, Arcam...) Oh, and wires try the Mapleshade bare copper wires ($90 from Mapleshade Records). You'll notice a HUGE difference and it won't cost you very much.
Good Luck, Kurt
