Have you heard the MA8900? The MAC sound is quite different than most amplifiers out there, very detailed and neutral very good across all frequencies. The sound is not hard and not harsh ever, this allows you too really listen at loud levels for long periods without fatigue. Also, McIntosh amps provide a wealth of features most amps just dont have, not to mention youll be living with it for a really long time because these things rarely have any problems. MAC is the MAYTAG of audio. Im not saying this of all their products (god knows they make a lot) but MAC amps are very good indeed.
