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

Three things going on.

Room is too small for panel speakers.

You’ll likely not find an amp that has high current AND great sonics in your price range.

Magnepans are never going to have a deep soundstage. It’s the nature of the beast. They do what they do well, but aren’t all things to all men.

I say this as a former Maggie owner.

I would look on Audiogon or another site for any vintage Classe Amp with 200 wattsper channel. CA200, CLASSE 15. something like that. You might get lucky. 

They are good power hungry panels, but they do reward you when you feed them well.

Many years ago I tried a Classe CA-200 on a pair of 3.5rs and I didn’t think it was a good match. I didn’t keep the amp long at all.

I'm reading posts from people telling you , your room is too small, get a tube amp and so on.  My first pair of Maggie's I listened to them in a small room, I still enjoyed them. Of course after I moved and got a larger place, they sounded much better.  There are so many people saying, it's not the watts, it's the current,  guess what, good high powered amps have high current to push those panels. As I stated earlier along with a few others,  look for and older Classe, Parasound,  older amps in that power and class range.  Enjoy the Music...

On a budget the Adcom 555 is tough to beat!
