Simply put, the REF150 SE is a breakthrough in stereo power amplification. The REF150 SE offers more power, greater dynamic thrust, a more vivid and resolved presentation, greater finesse, and quieter operation. Having identical outer dimensions as its predecessor, the REF150 SE has much more packed into its chassis.
New-in-box Audio Research REF150SE Stereo Power Amplifier in Silver or Black finish. Unit is brand-new, factory sealed and comes with a full factory warranty.

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.)
300K ohms Balanced.
Non-inverting. Balanced input pin 2+ (IEC-268).
16 ohms, 8 ohms, 4 ohms.
Approximately 0.6dB 16 ohm load to open circuit (Damping factor approximately 14).
