VTL or Audio Research?

I own a pair of Magnepan 3.6's and am looking for an amp to drive them. Any opinions on the sound of VTL MB 450 versus the Audio Research VT200?
I think VTL builds an excellent product. I think their ST-85 is a best buy. The VTL sound is a little leaner and cooler than Audio Research. AR is a little warmer and has great detail. I prefer AR equipment myself, though not by much. I feel the two brands are equivalent in quality. You just have to decide which flavor you prefer.
I use a ARC VT100MK3 driving martin logan odeyseys with mind blowing results never heard the vtl JK
