Audio Research LS 28SE Preamplifier

LS28SE Line-Stage

A high-end preamplifier in its technical performance. An instrument in its ability to deliver a realistic and emotional connection to the music.

The LS28SE draws on Audio Research’s experience creating, of all things, our Reference 160-series power amplifiers. Numerous costly component upgrades elevate the LS28SE’s clarity, resolution, transient snap, and sense of space. The relaxed purity and natural sense of balance are instantly noticeable and will inspire extended listening sessions.

Flexible operation
The LS28SE line stage offers flexible and intuitive operation. Four balanced and four single-ended inputs, and two sets of both balanced and single-ended outputs allow maximum connectivity. Input naming, tube hours, auto shutdown, and the assignment of home theater passthrough are all easily directed through the menu. Phase invert and mono are also standard functions.

The impact of a great preamplifier on your music system must not be ignored.

While loudspeakers and power amplifiers are obviously critical to the sound you hear, preamplifiers are often underestimated. Musical stones lay unturned because most preamps do not stand up to the caliber of the system in which they reside. Enter LS28SE. Its organic tone and inner detail bring an instant vitality and refinement to systems formerly employing other preamplifiers
