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.

Mark Levinson
McIntosh
Bryston

Thanks guys

The Emotiva XPA 5, XPA 2 do a great job on the 1.6's/1.7's. Maybe try them out before trying more expensive amps. The Magnepan/Emotiva combo makes a first rate system at a very afordable price.
