Audio Research Reference SE

Ref-75se

The engineers and designers at Audio Research have been hard at work creating a new series of Reference power amplifiers. After announcing that the GS150 amplifier would feature the new KT150 output tube, they were asked whether these would be incorporated into the Reference amplifiers. Not satisfied with merely changing output tubes, Audio Research decided to also include substantial performance upgrades in the Reference amplifiers to coincide with the changeover to the KT150. In addition to changing from the KT120 to the KT150 output tube, there are a number of active and passive parts changes in the SE amplifiers that result in “dramatic sonic improvements”. Existing Reference 75, 150, and 250 amplifiers can be fully upgraded to include all SE enhancements.
