My take: 

(1) 50K-foot level overview in general:… repost…

Audio - amps vs speakers 

The philosophy is clear. An affordable speaker with decent amplification (and source) makes a lot more sense than an expensive speaker with a cheap amp (and source.)

 Amplifier power ratings

Another word on power:, if your speakers are demanding to drive you’ll need a suitably muscular amplifier to support them.

Don’t look only at the posted headline power figure - watts per channel  (wpc) in isolation are meaningless.

Do consider It’s available “grunt ” ,,,,(ergo  the amplifier’s available current measured in amps that matters most. )

Go see what happens when the speaker impedance drops to four ohms. If the number nearly doubles, then your amplifier has good current delivery and will be capable of driving more demanding speakers.

(2) Lots of background reading available…. Do your own research , here is just a sampler.
