Audio Research Reference 150 SE 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.

150 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 150 watts, below 0.03% at 1 watt. Approximate actual power available at ‘clipping’ 160 watts (1kHz). (Note that actual power output is dependent upon both line voltage and ‘condition’ i. e. if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
(-3dB points) 5Hz to 80kHz.
(-3dB points at 1 watt) 0.5Hz to 120 kHz.
2.0V RMS BAL for rated output. (24 dB Bal gain into 8 ohms.)
