What's better 100w class a or 200w class ab?

This link may help - has description of class "A" and "B" amps.

Bear, I like the reality check. But Musical Fidelity rates it 72 amps "peak-to-peak output current". Is this some trick to make things sound better than they really are? Like NADs "dynamic power"?
Sure sounds a lot more impressive than their 3.2 integrated's measly 24 amps "peak to peak".

Interesting point Audiomax. Too bad more companies don't print max current. Creek would advertise peak current of over 30 amps I think but never in their specs. I can subjectively agree with Drrdiamond about Krell as their integrated is punchy.
Musical Fidelity now publishes this info:

A3.2 integrated 115 watts: peak to peak output current 24 amps.
A3.2 power amp 130 watts:72 amps
A308 integrated 150 watts: 48 amps
A308 power amp 250 watts: 72 amps
From listening, the higher current gives a crisper sound. Also there is more detail possibly because the high current fully magnifies every small detail.
I can also subjectively say going from N804 to N802 and ATC active 20 to ATC active 100 the bigger speaker presented more detail. Again, I think because of the higher power and ease of presentation that a larger speaker can do.
This is all a little off track but hopefully interesting.
