Audio Research LS28 SE

The LS28 SE line stage is a flexible and intuitive preamplifier. Four balanced and four single-ended inputs, and two sets of both balanced and single-ended outputs, allow maximum connectivity. The straightforward menu allows control of numerous parameters, including input naming, tube hours, auto shutdown, and home theater passthrough. Phase invert and mono are also standard functions. At the heart of the LS28 SE are four 6H30 vacuum tubes in the analog circuit. While the LS28 SE is the perfect match for any Audio Research amplifier, it has been designed to work with nearly any amplifier on the market today.
