IMHO the most important aspect of selecting a pro-type power amp for your speakers is how
loud you need to play.
The sensitivity rating of the speaker tells you how loud you can expect the speaker to
play with a known amount of power.
With an Solid State rig you should have enough power so you don't have to drive the
power amp into frequent clipping to get the volume you need. Amplifier clipping heats
up speaker voice coils faster than the same amount of clean power. So an amplifier
clipping all the time can damage your speakers faster than driving the speakers at the
same volume with clean power.
Tube amps are slightly different in that we like to drive the amp into distortion. And tube
amps will continue to drive more power than their spec sheet rating as we drive them
harder into clipping. In this case we just need to be sure that the speaker voice coils
can handle the heat generated by the tube amp. But the OP is looking at solid state
Selecting an amplifier with a power/impedance rating similar to the speaker "continuous"
power handling/impedance usually will give good results.
I've personally use amps rated at about 400 watts @ 8 ohms for years in my stage rig
and never blown a speaker by over-powering or under-powering.
