Good match for Adcom 555?

Hi all.

I'm putting a second system together of all old components that I've heard in the past and been impressed with. So far, I've got a Heybrook TT2 turntable and an Adcom 555 amp. Question is what speakers would be a good match with the amp. Doesn't matter if they're floor standing or stand mounts, they just have to be relatively cheap--say, 400-800 a pair. Used is fine, as you might guess....

Oh, preamp will probably be either a CJ PV9 or PV10.

Thoughts appreciated.

Bob
