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.
Buyer pays shipping and PayPal cost, if used.  Can pay by check and will ship when check clears.
