The Horror

If Gryphon/AGD sound dazzled you, it might be time to set up the Maggie as a Asian wall divider (rest its speakering duties for a few months, let the old lass rest). Get a Borresen X2, before any price hikes.

The rest of your electronics should be just fine.

I would get rid of that goofball Martin Logan sub and get a Rythmik FM8 subwoofer (considering that you may have a Borresen and Maggie as speakers).

Much of audio group Denmark’s tricks revolve around their unique noise mitigation solutions, which can dazzle many dudes perceptually. You can do it affordably with their AXXESS line of cables and power conditioners. Otherwise, spend a little extra on the Ansuz (mainz) power conditioner.

Last, but, not the least, if a small (setup restrictions, etc) and untreated room is all you can do....lower all expectations, have several swigs of whisky, renounce everything and become a wandering monk.

Maggie’s are very hard sometimes impossible to get set up optimally in most people’s rooms and without that everything else is bottlenecked. I’d focus on that. I had them for years and ended up punting and going with relatively affordable Ohms.

Also learned the lesson throwing money at a problem alone does not solve it.

The best sound comes from good quality and well matched gear that works well for one in their room. Need not cost like a Tesla at all.

If you like to listen to genres including modern pop and more electronic instrument based music, Maggie’s are really not designed to do that well like most good quality designs with more traditional dynamic drivers.

The only real audiophiles own Formula 1 teams.

You have a very nice system, but it seems you are really forcing the Magnepans into that space. Seriously, consider some high quality stand mounts, you can find that bliss. 

@zlone +1.

My suggestion would be a pair of KEF R3 meta on stands. Optionally add matching kef sub tuned in just right for that room and you are in very good shape.
