Budget AV Receiver with Magnepan

I'm looking to build a 5 channel home theater/music system using Magnepan MMG-W's and CC2 (or possibly MC1's for FR and FL) with a Monitor Audio sub. Now I'm looking at inexpensive used high end AV receivers to tie it all together:

Rotel - 1055 75x5

NAD - T744 (can be had refurbished with warranty) 5x50W, not sure if this is enough to drive the Magnepans?

NAD - T754, a bit more power, can be had with warranty

B&K AVR 202 - 105 x 5, I've heard one of these and liked it, it's a bit older than the rest

Cambridge Audio 540R - 80 x 6, nice looking unit but haven't heard much about them compared to NAD/Rotel/B&K

And advice/experience on any of these would be greatly appreciated. I'm happy with 5 channel DTS, don't need HDMI (although would be nice), want something that can drive the small Maggies without struggling (don't need ground shaking volume here), and I want something that sounds *good*. I'm coming from a small Denon 75w x 5 Dobly Digital surround receiver (driving Monitor Audio Silver 5i's). I know seperates are better, but I'm trying to keep the wife happy ($$$). Thanks!
