Which solid state amp for Von Schweikert VR-4.5?


Am still looking for a good solid state amp to drive my VR 4.5's. Looking to spend under $1500 used. Want detail and as clean a sound as I can get for the money. Not looking for smooth or euphonic amps. Preamp is tube unit (6SN7's). Considering Parasound A21, McCormack DNA-1 (too smooth?), Classe CA-150/151/200/201, Pass X150, CIA D-200. What amp(s) would you recommend?

I am using Bel Canto Class D amps with my VR-4s and a Modwright tubed pre-amp. I like this combination. Bel Canto will let you use them on trial if you want to try them out in your system.
As a follow up, I ended up with the McCormack DNA-1 amp. Lots of power, finesse, and great soundstage. Am considering having SMC do the upgrade mod. I think this amp, even stock, is a fine match for these speakers.
Anybody notice they killed the 'Audiogon fees' thread in miscellaneous audio section?

Tube540,
Getting back on topic here.
An excellent choice! Honestly, given you list I don't think you would have lost with any of them.
I own a pair of 4.5's as well and power them with Simaudio W5.
I used to own a DNA-1 Deluxe in a different system and it was really a terrific amp - certainly NOT too smooth. You may not even feel the need to do the SMc mods especially given the expense. I sold it in an upgraditis mode (and wanting balanced outputs) but wish I still had that amp.

I am going to try biamping with a tube amp for the highs and keep the W5 for the lows. You may want to consider that for the price of the amp upgrade.
Check out the Von Schweikert Audio forum on AudioCircle where Albert himself makes this very suggestion. No active crossover required!!!
