Big Step Up from Totem Hawks? 10k Speakers?

I'm looking to upgrade my Totem Hawks in a big way. Honestly,I have been extremely impressed with them. As I've moved up in electronics, the Hawks have kept up. But now, it's pretty clear they are the weak link in my system. My budget is a max of $12k, (it went up after I heard the MBL 126 at a show, they go for $12k) I generally like the small floorstander type, but I'm open to opinions. The room is 18'x15'. What will match up well with my class d Nuforce monoblocks with Modwright tube pre? (a fabulous combo, muscular yet musical) System: Clearaudio tt,Modwright LS100, Nuforce V3 SE,all Synergistic Research cabling and conditioning. Thanks for your time and opinions!
