Would like to seek advise if any budget used s/s amp($600-800) can best match with LS8 to drive Proac studio 125 spk? before that i'm using MF A3.2 int amp which full range incl. vocal is good especially the mid -high, i like very much. But the bass is too much, fat & boom.

Actually I read some valuable review here & other site made some choice below,
ARC : D-100,D-120,D-130
Classe : DR-9, P-101
Does any one of them ok ? Or pls recomend if other brand also great?

Highly appreciate and thanks to any help & response to such a newbie.
