NHT Classic 4 or AV123 Strata Mini?

I am in the market for some new speakers and what I am trying to accomplish is getting rid of a powered sub.
My room size 12FT wide by 17FT Long.
I will be driving them with a Wyred 4 Sound ST-250
Any thoughts of which one would work best for my situation.
Or any other Tower Speaker New or used that would fit.
Thanks for your help!
What is your maximum budget ? What kind of music do you listen to? Etc...
I ended up Buying a pair of Definitive Technology BP7004's
I got a great deal that I could not refuse.
