It hard to say. ML2 has its own issues (and partially if you prefer to buy new) and many speakers that might work with ML2 do have their own issues. Owl was correct insisting for over 100dB sensitively and high impedance for ML2. There is very little if any out there that might fit the bill.
Among the owls list:
Magico: they are ultimate foolish loudspeakers and they pretty much embraced all foolishness that an ignorant designer can stink into a loudspeaker.
Avantgarde Trio: have a lot of issues and might require a lot of work and experience to get a more or less civilized sound out of them. I doubt that it will be possible without a fundamental rebilling them.
Edgarhorn: it is hard to say. Bruce doe good speakers but au to the limited price point. Also, all of his customers are or dupes or juts not serious fools. No one even used Edgarhorn with ML2-level of electronics.
Siemens Klangfilms: Dispute to the flashy paranoia the recently was purely artificial created around them they are juts bad and none-interesting speakers with huge amount of problems and with complete inability of the speakers users to deal with them. This all is just a sweet audio myth and nothing else.
Tannoy GRF: The have some bass problems typical for dipole J-horns but they still listenable. Nevertheless I would not consider them as something around which I would bult a room. They are juts a very good drop in monitors.
Kharma Grand Ceramique: Unspeakably horrible loudspeaker with huge amount of problems. They have the worst in the industry ratio between the misery of sound and price.
Von Schveikert VR6: They are quite dead. Although I head them just once but I did not detect that they were in any way different then all the rest Schveikerts speakers. You heard one-box speakers with a bunch of crappy driver then you heard them all.
Wilson Maxx2: I do not think that Wilson is the loudspeaker of ML2 level. Lamm in his web site suggests using ML2 with 94dB sensitively but it is he dose it juts to sell more of his amps. The largest Wilsons (Slams, Alexandria) surprisingly do not have this typical dynamic compression of the box loudspeakers but each of the still have a lot of issues for the price they cost.
I usually do not provide purchasing recommendations. However, in your case I would warn you that instead of buying a 50K worth not-well performing loudspeaker you might get a better cost-per-transaction yield if you spend 10K for some kind of Kharma3.2/GRF level acoustic system and then work on the rest of you setup. For instance the Wadia front-end skew up sound much more aggressively than a bad loudspeaker. Also, beware about the new EMM gear it might be quite dangerous thing.
