Monitor selection

I hope you guys can help me out with my dilemma. My system consists of:
Ah! Njoe Tjeob CDP with the Burr Brown OPA627 Op-amp upgrade
Van Den Hul The Bay C5 IC
Parasound HCA 750 power amp
Acoustic Research speaker wire (to be replaced soon)
Magnepan MMG

The problem is that I don’t get much clarity and detail from the MMGs, so I plan to sell them and buy some used monitors. I need some monitors that are bright and have really good midrange, bass is not really critical because I have a subwoofer. I’m in a cramped dorm room measuring 14 x 21, and I can only spend about $700, maybe $800. Here is a list of used speakers that I found in my price range.

Totem Model One
Meadowlark Audio Vireos
B&W CDM1NT
Vienna Acoustics Haydn
PSB Stratus MINI
Omega TS-1 R
Angstrom Legato
Silverline SR-11
Soliloquy 5.0
Linn Katan

I need some help in deciding which one to buy, also let me know if there are better monitors out there.

Thanks
