I would have to agree with Audiomax....current drives the loudspeaker. Amperage, not wattage is the key. I have heard some rather gawdawful hi-wattage amps, and have also experienced the fidelity and depth of sound that that a high-current, though lower wattage device can provide.
If you can, try to listen to both amps under identical conditions...same program material, same preamp, same cables, same speakers. That is, if you can... this is not a perfect world.
