Used. These are powered speakers that can be used with a turntable without the need of a receiver or amplifier. Has lots of inputs and comes with power cord, RCA cable, USB cable, speaker wire, and remote. Has scuffs and scratches (see pictures). Originally retailed for $500 and I am pricing it based on eBay, but will take offers as well. Ideally need to get rid of before Jan. 31st. Pickup on Stanford campus please. Will try to plug in to show it works depending where you can pick it up. Specs here (except mine is not refurbished):
