being honest i dont know. but stanton arent a big name in studio monitors and, although they used KRK technology, i'd still be inclined to go with a company that have a track record.
try KRK themselves, m-audio, alesis, yamaha etc
check out the future music monitor showdown.. its on the web somewhere
also while i think of it, check out samson rubicons.. they're meant to be quite good.
