REFERENCE 150 SE

STEREO POWER AMPLIFIER

Simply put, the REF150 SE is a breakthrough in stereo power
amplification.  Replacing the REF150—which was one of the most respected
modern stereo amplifiers—was a daunting task, but it has been
accomplished.  The REF150 SE offers more power, greater dynamic thrust, a
more vivid and resolved presentation, greater finesse, and quieter
operation.  It is the new benchmark. Having identical outer dimensions
as its predecessor, the REF150 SE has much more packed into its
chassis.  Refined front-panel cosmetics reflect the updated look of
current-generation models, with silver units having silver handles and
silver top covers, while black units have black handles and black
cover.  (Colors may be mixed to match older models.)

The REF150 SE is a fully-balanced design, so its inputs are
balanced XLR only.  It has a 20-amp IEC power connector, 4-8-16 ohm
output taps and 12V triggers arrayed on the rear panel.  Under the top
cover there are a number of circuit enhancements resulting in stunningly
improved performance.

First, power-supply energy storage has
been doubled to some 1040 joules.  All-new interstage coupling
capacitors using technology and materials first incorporated in our
Anniversary Edition preamplifier effortlessly link input stage to output
stage, which is powered by two matched quads of Russian KT150 output
tubes driven by 6H30 twin triodes.  There is more than ample multistage
solid-state regulation.  Output stage coupling is a combination of
“ultralinear” and Audio Research’s patented “partially cathode-coupled”
topology, which is superior to conventional pentode or triode operation.

Amp has 1318 hours on the SE tubes.  No marks on this unit. Comes in Original box,
with manual, and power cord.
