building the best system I can?

"Speakers sound like the amp running them,..."?

Wmbode, please forgive me, I was responding to the opening of Shubert's post.
I'm not that familiar with the Paradigm 20's v5's, so I'll refrain from making specific recommendations other than if they are like other Paradigm's I've heard, I'd personally consider other speakers first. YMMV.

Lowrider57, actually I would suggest starting with the speakers and then finding an appropriate amp, etc., etc.. Which the OP seems to be doing.
I just found Shubert's post somewhat curious.

I think you would be better offer considering how a given pre would match with the amp, before the speakers.

It depends on the particular McCormack amp, they have differing considerations.

B.limo, I have heard many, but not very recently, and didn't bother to remember what any of them were called.
