Magnepan, Ohm, Spatial or ??

Saw several Vandersteen 3A for sale used??

I have listened to Spatial at LInear Tube Audio, and PAP at shows. 
Both share many similar characteristics. As mentioned, min distance from wall behind baffle. Clear defined bass and great sound staging. 
Generally speaking, the room needs much less treatment than with most boxes. Both designs are highly efficient. SET amps may apply also. PAP xo’s allow future customization via a screwdriver. Caps, resisters, etc, can be changed in minutes to match your hatch. 
PAP has just come out with a product in your price range. Enjoy.

PAP?

With your budget, you could consider something like my own setup, which is a pair of Ohms augmented with a pair of subs.  I am a bit of a bass freak, and my Vandy subs will bust your budget unless you find them used, but a combo of the Ohm 1000s with a pair of subs would be my choice.  I am beyond thrilled with my Ohm 2000s after 10 years, and I have no desire to change speakers.

@soundchasr .. I listen to Jazz and Rock predominantly and at reasonable levels in my typically appointed 13’ x 18’ living room. The room has large archways on 2 walls.

I suspect a pair of Ohm speakers would be perfect for your room, they just don’t sound like Maggie’s, which are polar opposites in their presentation. Ohm’s are easier to place, very room friendly, have a very wide sweet spot, and a nice tonal balance. The MicroWalsh Talls benefit from a subwoofer or 2. The Maggies have better detail, image specificity, a smaller sweet spot, and also benefit from a sub. Both are wonderful speakers and is why I keep them. (I like variety and have enough storage space.) I’m using my MMG’s (with sub) now in fact, with a Marantz class d integrated. Sounds wonderful.
