Which Amp for Magnepan MG 3.6/R?

Many have asked which amp works best with the Magnepan MG 3.6/R, but I haven't seen a good response yet. Can anyone assist me?

My current short list includes the Classe CAM 350, Nelson Pass X250, Belles 350A, and Theta Dreadnaught II. Which one would you choose?

My system includes: Musical Fidelity NuVista 3D CD player, Klyne 7LX3.5 solid state preamp, a pair of Cambridge SoundWorks Newton P-1000 subwoofers, and Analysis Plus Crystal Oval 8 cabling. I listen to classical music and jazz.

Any help you can give would be greatly appreciated. Thanks.
