Audio Research 150SE Valve Power Amplifier, DEMO

Audio Research 150SE Valve Power Amplifier. DEMO (Total usage 219 hrs) "I’ve loved the REF 75 since first hearing it, but the REF 150 SE is a level beyond. The first REF 150 blew me away, yet the SE shows gains, especially in the bass, midband and stage width, one could not have anticipated. How much is due to KT150s, and how much is it due to new parts? I cannot say. Regardless, the upgrade borders on the supernatural. With both small and large ‘R’s, this is my new reference. Sound Quality: 88% 0 - - - - - - - - 100" Hi-FI NEWS & Record Review, Ken Kessler, Specifications Power Output: 150 watts per channel continuous from20Hz to 20kHz. 1kHz total Harmonic distortion is 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 the power line has high distortion, maximum power will be affected adversely, although from a listening standpoint, this is not very critical) Power Bandwidth: (-3dB points) 5Hz to 80kHz Frequency Response: (-3dB points at 1 watt) 0.5Hz to 120 kHz Input Sensitivity: 2.0V RMS BAL for rated output. (24 dB Bal gain into 8 ohms) Input Impedance: 300K ohms Balanced Output Polarity: Non-inverting. Balanced input pin 2+ (IEC-268) Output Taps: 16 ohms, 8 ohms, 4 ohms Power Output: 150 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 150 watts, below 0.03% at 1 watt. Output Taps: 16 ohms, 8 ohms, 4 ohms Output Regulation: Approximately 0.6dB 16-ohm load to open circuit. (Damping factor approximately 14) Overall Negative Feedback: 14dB Slew Rate: 13 volts/microsecond Rise Time: 2.0 microseconds Hum & Noise: Less than 0.1mV RMS – 114dB below rated output (IHF weighted, input shorted) Power Supply Energy Storage: Approximately 1040 joules. Power Requirements: 105- 125VAC 60Hz (210- 250VAC 50Hz) 730 watts at rated output, 900 watts maximum, 420 watts idle Tubes Required: 4 – Matched pair KT150 – Power Output; 4 – 6H30 Driver Dimensions: width: 19” (48.3 cm) height: 8.75” (22.2 cm) depth: 19.5” (49.5 cm) Handles extend 1.5” (3.8 cm) forward Weight: 75 lbs.
