About the LS28SE
The Audio Research LS28SE is a premium line-stage preamplifier that offers a blend of flexibility, intuitive control, and superior audio quality. It features four balanced and four single-ended inputs, along with two sets of both balanced and single-ended outputs, ensuring maximum connectivity. The preamplifier is equipped with a user-friendly menu system that allows users to control various parameters such as input naming, tube hours, auto shutdown, and home theater passthrough.
