I have an Arcam A75+ amp running B&W CDM1NT speakers. My CD player is the Cd92T. Although I'm happy with the sound, i do feel that the A75+ is struggling to drive the CDM's at high volumes. Will aiming for the A90 bring considerable improvement in the sound stakes due to its higher power ouput? I think there is no point in demoing as the CD92 and CDM1NT are both discontinued and the replacents are quite different in specification. No HDCD or Ring DCS for the CD93 Also in a previous thread Andy Arcam said that you can connect the preamp of the A75 to your sub. But my Paradigm PR8 (don't laugh) has only one line level input not two. Can I connect one of the preamp outputs to it?
