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. Two 6H30 twin triodes are at the heart of the Class A audio circuit. A custom designed power transformer provides serious current delivery. In concert, the components of the LS17 SE create a sound that will truly delight the listener – this is a preamplifier dedicated to delivering a great musical experience.About this unit
