FWIW - Watts ain't watts, you've got to know measurement conditions before even that measure is meaningful.
Anyway, your speaker manufacturer should provide you with a specification for minimum reccomended power & approximate nominal impedance. Once you have that in hand (e.g. 60 wpc continuous and 120wpc short term peak @ 4 ohms) then I'd reccomend looking at amps at and above that power range & trying to make the selection by listening to different amps paired to your speakers if at all possible.
It would be great if you could by the best sound just by looking at the numbers, but it doesn't work that way.
