I, and others, have asked several times in this thread for the power output in relation to ohm-load, but the question has been repeatedly ignored. It's not that some of us are being 'horrible', it's just irritating when a vendor announces something, tells everyone how much it rocks, but then seemingly ducks & dives legitimate questions.
