are magnepan mmg any good and intergrated amp suggestion for them

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. 

I have two systems. In one I have MMGs paired with a Parasound A21 and it’s a great match. I had them connected to my tube amp, but I think they draw too much power or current from the amp.
