Best Amp for Magnepan 1.7?

What would be the best amp out of the following four brands to power the new 1.7s? Also, would a monoblock setup be worth the extra money? I like McIntosh; however, I'm not sure if the detail and speed will be up to what the 1.7 would want.

Thanks guys
I'm using an Odyssey Stratos Dual Mono amplifier with Odyssey Candela Preamp for the Magnepan MMG's. I'm very pleased with this setup. I have 1.7's and can only imagine how amazing it will be.

The Odyssey gear is of great quality and offers amazing bang for the buck.
For what it is worth, I run MG1.2's wth a McIntosh MA 6300 integrated at 160 wpc into 4 ohms. Sounds good to me.

The efficiency of both speakers is about the same.
Magnepan's like a lot of current. I would choose between McCormack DNA-500, Clayton 100 watt or 200 watt Class A amps, or Modwright KWA 150. All these amps are superior to the Krells, Levinsons, Brystons, etc.
In Germany the Magnepans are distributed and often demoed with Jeff Rowland.
But i would second the Roger Sanders / Innersound amps!
