Amp suggestions

I would also consider looking for the XA60.5's at the top end of your budget. Always been impressed with their performance when auditioning at local dealers. If not for their size, I was considering switching from my current Rowland 312 to the Pass Labs XA100's.

Yes, I'm curious as to how the A21 sounds with the PSB's, and what models they are. For that matter, what's the rest of the system?

What is the rest of your system?

If you have balanced outputs from your preamp my Krell FPB 400 cx is for sale at less than your price range. Superb amp.

Thanks for all your input, The PSB,s are the Synchrony One B, Parasound P7 pre-amp, Rythmik Audio F-112 sub, VPI Classic One Turntable w/ Lyra Delos and Fosgate Signature pre-amp.

Although the PSB's are bookshelf, I'm satisfied with the mids , percussive bass depth and tightness with the Rythmik dialed in. My issue is how bass guitar is being reproduced. It's hard to explain, but bass notes have an almost annoying , over powering drone that distracts from the rest of the music. Tone controls on the P7 are off. I turned them on once and well you can guess the awful results. Maybe upgrading the amp is not the right step?
