GSi75 Mint Condition. Only 1131 hours 

Audio Research manufactures the highest quality tube equipment made today. The GSi75 has an all-in-one design that gives you a streamlined look and more convenience without sacrificing quality.

• Includes preamplifier, amplifier, phono stage, DAC (digital to analog converter), and headphone amp
• Amplifier uses KT150 output tubes 
• DAC handles almost any sampling frequency including DSD. 
• Phono stage for turntable
• Headphone amplifier 
• Includes internal high pass100 Hz filter, factory installed, to roll off signal (6 db per octave) for Vandersteen speakers and subwoofers, which can be removed if desired.
• Elegant, striking industrial design

• Specifications:

  POWER OUTPUT	75 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1.5% at 75 watts, .05% at 1 watt. Approximate actual power available at ‚¬œclipping‚¬? 80 watts (1kHz). (Note that actual power output is dependent upon both line voltage and ‚¬œcondition‚¬? i.e.: if 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)  12Hz to 70kHz.
  FREQUENCY RESPONSE	(-3dB points at 1 watt)  1.0Hz to 70 kHz.
  INPUT SENSITIVITY	0.55V RMS Single-ended for rated output. (32.5dB gain into 8 ohms.)
  INPUT IMPEDANCE	52.5K ohms Single-ended.
  INPUTS	SE1, SE2, SE3, Phono, S/PDIF digital (coax RCA and Toslink), USB
  MAXIMUM INPUT	10V RMS (any input).
  OUTPUT POLARITY	Non-Inverting (any input).
  OUTPUT TAPS	8 ohms, 4 ohms.
  OUTPUT REGULATION	Approximately 2dB 8 ohm load to open circuit (Damping factor approximately 4).
  OVERALL NEGATIVE FEEDBACK	4dB.
  SLEW RATE	10 volts/microsecond.
  RISE TIME	4 microseconds.
  HUM & NOISE	Less than 1.0 mV RMS -88dB below rated output (IHF weighted, Vol down).
  CONTROLS	Rotary volume (103 steps), Rotary input selector, Power, Mute, Bias.
  DIGITAL SAMPLE RATES	44.1kHz to 192kHz, SPDIF and USB 2.0 HS, DSD USB 2.0 HS
  MASTER OSCILLATOR	22.579mHz ±20Hz for 44.1, 88.2 & 176.4kHz. 24.576mHz ±20Hz for 48, 96 & 192kHz sample rates.
  INTRINSIC JITTER	<10ps
  POWER SUPPLIES	Electronically regulated Low and High voltage supplies for input stages. Automatic 40 sec. warm-up/brown-out mute.
  POWER SUPPLY ENERGY STORAGE	Approximately 350 joules.
  POWER REQUIREMENTS100-125VAC 60Hz (200-250VAC 50Hz)	400 watts at rated output, 600 watts maximum, 210 watts at ‚¬œidle‚¬„: 1.0 watt power off.
  TUBES REQUIRED	2-Matched pair KT150-Power Output; 2 -6H30 driver.
