SEXYTIME!! NIIICE!
Well I cant really say anything about the O 'cause it isnt out yet, but my guess would be that it would be slightly better than the K in both SQ and SPL, probably just has a step up in build quality and engineering. Id say the USX600D would be a pretty good match for the K 12, although I dont have any experience with it...
