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.
