...say it does have better attack/reaction
= slew rate?
This is how Tom Cumberland summed up the A1400. Tons of power + better slew rate/speed = better amp.
When I asked how much power the M80s need, Debbie gave the usual "any 100wamp will do" answer. Tom didn't miss a beat... "A kilowatt."
It took a bit of browbeating by Debbie to get Tom to admit you could drive the M80s with a 100w amp, but he really believes you need a lot more power to get the best out of them. The exchange was quite entertaining.
