Speakers more fussy about cables than amp?

Hey guys, I think I wrote my question rather ambiguously.

In my system, I've tried a couple different amps that seemed pretty fine. And found that speaker cables could make a big difference in presentation.

My conclusion/supposition is that when people talk about trying to find the correct amp-speaker combination, maybe it's rather the case that it's the speaker-speaker cable that's more of a variable!
