"Audio Research’s GS150 might have some styling cues from yesteryear that could have you thinking its sound will be old-school as well, but I didn’t find that to be the case. It’s a thoroughly modern-sounding amplifier that passes music along with high accuracy, completely devoid of the kinds of colorations heard from more traditional tubed designs. Although the GS150’s lack of such colorations might not be the cup of tea of those who, like our own Jason Thorpe, live for the old-time tube sound, its adeptness at re-creating recorded space will probably win them back. For those who want a neutral sound, excellent resolution, high power, ease of use (for a tubed amp), superb build quality, and beautiful industrial design, Audio Research’s GS150 is very tough to beat."

155 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 155 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).
8 ohms, 4 ohms.
