I kind of hate bringing up an old thread, but this one in particular interests me, because I have a pair of mint Sony SS-K90ED towers out in the garage (2-car garage which has been sealed off, insulated, sound deadened and air conditioned). Once I get my system moved over here, I plan on giving those Sony's a try and see how they sound in my system. With the M-500t MkII's and a 4000t in front of them, I'm sure they'll perform.
Pics will follow at some point. Possibly later this coming weekend.
