Which One Amp for the Magnepan 3.6's?


Given a choice to drive a pair of Magnepan 3.6's in a large room, which amp would you choose (assuming the use of a tube preamp):

ParaSound JC-1 monoblocks

ParaSound A-21 stereo

Krell 250a

Didn't Audio Research just introduce an amp at CES that is supposed to be a great match to Magnepans? I saw it in one of the CES recaps on Stereophile, I believe.
Sunfire Signature(600Wpc) load invariant amp is the best so far from Bob Carver.
Can anyone comment on the ParaSound JC-1's? What 'kind' of sound does it have? Strengths, weaknesses...
But why not Spectron Musician III Mk II fully upgraded which is today available at special price? You can read a lot about it here around. Needless to say that is great match with planers.
