If you're ok with a used integrated amp, the Primare I-30 would be a good choice. There are lots of good reviews on this integrated amp out there.
Best Integrated Amp for PSB Image T6 Speakers
I currently have an NAD C356BEE driving my PSB Image T6 speakers and am not too happy with the sound. Despite "tuning" the placement of the speakers numerous times, the music still sounds flat. The room is large (18'x26') and my listening position is about 12' from the speakers. I hooked up a friends old NAD receiver (C740, 35 WPC) and the system sounded better. Any suggestions on a different int amp? Thanks.
