Magnepan 1.7 i - Amp suggestions

Bryston makes some very nice equipment... And has models with the power you need. 

Bryston and Magnepan are like peanut butter and jelly.  OK corny but true.   A bit pricey for used but maybe just buy an old 4B from on here they are out of warranty then you are in your price range.  I would also buy that used BP26 and MPS2 because at 1600 bucks you need those.  Hell yeah Bryston is great gear.  Who else does a 20 year warranty?  Better yet they are great folks too and willing to chat about their gear which is always nice if you feel like chatting.  Buy buy buy

Oh and BTW the 4BSST and the BP20 and MPS1 I am using in my second system with these LRS is kick butt.  Rock and roll the bass is back but you gotta know how to place them and frankly I do.  I got the Mag fever and I know the cure.

This Van Alstine 400R would be a good fit with the Maggies!

I have Magnepan 1.7i.  Avoid Schiit Vidar. I tried those and one went into thermal protection. Then switched to Bryston. Journey over. I had one then two of the 4B3s used as monoblocks. That’s all you need. I later got an amazing deal on a pair of 28B3s. So that is what I have driving my Magnepan 1.7i speakers now. So much head room for dynamics and transients. What I would also recommend are the MyeStands from Grant VanderMye. Also the Mike Powell fuse and jumper upgrade. With those you will be all set. You will have tighter and better bass and crisper cymbals. Enjoy!
