I am at the same decision point having just ordered an Audio Refinement Pre2/DSP (and will wait for the upgrade card). I have whittled the list of amp candidates to:
Pass X5
EAD powermaster 500 or 1000
Krell kav500
Sherbourne 5/1500
Linn AV5125
Bryston 9BSST
Pass is the first choice but damned expensive. The EAD seems an excellent value. Any of these amps will drive just about anything adequately short of speakers with very demanding (read: LOW) resistance. We are using Gallo Due speakers with a REL Acoustics Strata II woofer.
