Best Cheap Amps for Magneplanar Speakers

Magnepan like many less efficient speaker makers do not emphasize the benefits of more power with their products probably to not limit market or discourage customers.   Less watts will work but you will run out of juice if the volume needs to go up.    Current probably does not hurt but I did find Maggies not as needy there as with many less efficient dynamic designs.  Tube amps even work well if powerful enough to get the volume you want.

My local dealer has sold Maggies for years and recommends Class D amps by Rogue for use with Maggies though they sell tube amps also.  

A lot of good suggestions.

I would second two:

1. Parasound Halo A21 makes Maggie’s sing as good as I’ve heard them (except for the Halo JC1 monoblocks) - about $1500 used.

2. Classdaudio SDS 470C makes them sound as good, maybe better - about $700 new.

I’ve got all of these to drive my Magnestand 1.6’s (Maggie 1.6’s on steroids). They’re all superb.

Tube amps give them great mids, but struggle with bass and dynamics with Maggies (I’ve got some of the best - Atmasphere M60’s with Zeroformers). With Maggies, I prefer good SS amps with a good tube preamp - which gives you a great blend of both.

If your budget won’t allow the tube preamp right now - I’d be looking for a hybrid integrated (e.g. Rogue Pharoah, Peachtree, etc.).

At one point in time (5 years ago or so) I used a pair of the Wired4Sound SX1000R monoblocks with my Maggie 1.6's with good success. I also believe that the CIAudio would work well since I owned them also. I only suggest this to you because I'm trying to hold the cost down, especially if you can find them on the used market.
I do like several of the other options that others have mentioned.

Was driving my 1.7s with an Acurus A150 until last night when my used Bryston 4b arrived. Clear upgrade in the bass dept and the immediate response. Highly recommend Bryston. If you want monos then get 2 and bridge them. Tube preamp really finishes the package.
