Budget amp that will give Magnepan 3.6Rs better depth of soundstage

If you don’t mind an older amp, look for a Proceed HPA-2. it is 250 w/ch at 8 and 500 w/ch at 4 ohms, good down to 2 ohms and will drive virtually anything with a neutral sound and a black background. Know that you will be buying about a 20-yr old amp.

The good news is that its design shares the basic features of dual mono Levinson amps. There are three authorized Levinson service firms that will repair them, if needed, Pyramid Audio in Austin, TX is one of them and does great work, having used them myself. One warning - the amp weighs over 80 lbs. For any needed repairs, however, each of the two amp modules can be separately removed from the case. A local repair firm, technician or Levinson dealer can help with that. They are available used for under $1,000. I have one and it is still going strong. It is a great prescription for any low efficiency, power hungry speaker that requires high current.

Too much speaker for too little a room.  Knock out a couple of walls.  

I agree that those speakers are too big for the room. I would move down to 1.7’s. Which are excellent.

A used Schiit Vidar can be found in the $600 range.

I had Maggie 3.6Rs on loan for close to 20 days in a 12’ x 16’ room with a 220 wpc dual mono solid state amp with 75amps of current. A capable amp.. The room was the limiting factor. Just did not work very well at all. Sound stage was all wrong.

Same day of evaluation, swapped in a friends pair of much smaller pair of Maggie SMG-Cs just for grins (at his suggestion) and it was drastically better. It was a quick lesson in room acoustics and speaker response. Needed a much bigger room in retrospect.
