Excellent preamp by BV Audio, a short lived company put together by some MIT techs. Very hard to find. Has balanced and RCA ins and outs. Excellent phono stage which can be finely adjusted for any cartridge by changing dip switches internally. Full function remote, Inputs can be named. No issues except for scratch on top, not visible from front. Non smoking house. Google BV Audio for review from TNT-audio. Very detailed and musical pre. Please see my listing for the matching power amp. Will include Signal Cable power cord at my asking price. If you have no feedback do not contact me.
