The LS17 SE builds on the architecture of the LS17 and adds SE upgrades to provide exceptional performance. New Teflon coupling capacitors as well as other internal performance enhancements combine to create a preamplifier offering greater detail, spatial cues and dynamic breadth.
About this unit
Fantastic condition trade-in Audio Research LS17 SE Linestage Preamplifier in Black finish. Preamp comes in original packaging with remote control, power cord, and printed owner's manual.
Unit is rated 7/10 for minor cosmetic wear, including one small nick on top edge of the faceplate and two tiny nicks on top edge of backside of unit (see photos). Battery cover for remote control is functional and intact, but loose.SPECIFICATIONS
