are magnepan mmg any good and intergrated amp suggestion for them

I use MMGs with a pair of subwoofers in a second system.  The total cost of the speakers+subs was +/- $1600.  I'm not sure that anything on the market matches that combo for full range performance for the $.  As some have noted, there are quirks (tight sweet spot, power requirements, room placement), but the MMG really offers a compelling value proposition, IMO.

PS Some argue that they're tough to mate with subs, but - particularly with room corrected subs or amplification - I haven't found that to be the case at all.  YMMV.

Yes, they are really good.  I have had a pair of mg12, and two pairs of mmgs in my life.  Just keep in mind that they are a one listener speaker (very directional).
I like the nad suggestion; it makes a killer budget stereo.
on the mmg, make sure to bypass the fuse....they sound so much cleaner and dynamic without.  It's a very easy surgery.

Second on the , "bypass the fuse" suggestion(as long as you never clip your amp/exercise restraint). I’m using MMG’s for home theatre fronts and MG12’s, for mains, in my biamped system. Both bypassed(fuses and attenuation resistor connection), along with WBT 5 ways(and other mods).

I owned a pair of MMG's before and I loved them. They do need to be placed a few feet away from the back wall with a little bit of toe-in to sound properly IMO. The sweet spot is narrow due to the design of these speakers. A pair of after-market stands to level them up to your ear level would help for sure. Without a subwoofer like DWM, MMG's sounded very good already. They will amaze you if you pair them with a DWM or a fast cone subwoofer. The MMG's are very revealing so the quality of the amp is also important. I tried Adcom, Vincent, Hegel and Class-D with the MMG's before. Hegel sounded the best but it's probably above your budget. I'd suggest a used Vincent SV-236 hybrid Integrated amp if you can find one.

I might recommend Hegel too much but Hegel does match well with Maggie's although I don't know this model of maggies. Hegels are expensive but the older lines are going for a decent price like the h100, etc. the nad is a good idea too esp if you find a good one second hand.
