Amp for Virgo III's

My current system consists of a Well Tempered Classic turntable/arm with Micro Benz ACE for analog, Benchmark DAC 1 for digital, Audible Illusions M3A preamp.

I'm thinking of upgrading my PSE Studio IV solid state amp to something used in the < $2000 range to drive my Audio Physic Virgo III's. I value speed and detail, imaging, extended but not overly bright highs, tight bass, and good dynamics.

I have the following to possibly choose from, none of which I've actually been able to audition (yet):

Krell KSA-200S
Musical Fidelity A3.2 amp
Audio Research VT-100 Mk II
Cary SLA-M100s
Primare D-30.2
Melos 202 Gold
Michael Yee PA-2
McCormack DNA-1
Electron Kinetics Eagle Two
Aloia PST 13.01

I am not looking for a marginal improvement, so maybe I should just stay where I'm at -- but I would appreciate any recommendations and the reasons for your particular choice(s) if you think there is one or more of these that would be a significant improvement.

Thanks,
