What do folks mean by slow? The Mac MC402 I have is not slow like a Cary tube amp (older ones). If an amp has meat and body, then one calls it slow. When an amp is more threadbare, then some mistake this for speed. Well the newer Mac amps play as fast as any amp. Great thing is they do it with body and soul. Bass is full, the midrange is wonderful and the highs never overbearing. All I know is the Mac 402 in my system plays a 4 minute song in 4 minutes. If it did so without tonality, meat and decay it would not be faster, but rather a Sears MCS receiver.
