We are a Reference Audio Research Dealer. We can Demonstrate this unit in our Store.
We have 1 unit of VSi75 with KT-120 Tubes.
( This unit has been discontinued and replaced with a VSi75 with KT-150 Tubes which now retails at $9500.00 )
This is a very polished and refined Integrated Amplifier.
The tubed integrated amplifier is the ne plus ultra of audio. Strong words, those -- fighting words, even. But think it through: The tube integrated is the Platonic ideal of amplification. It’s one box that performs all the required, necessary tasks -- and nothing more.
Audio Research knows something about making long-lasting, good-sounding, rugged gear. Founded in 1970, ARC has been making audio products for nearly as long as I’ve been alive, and though they’re now owned by the Fine Sounds Group, they still will service any and every unit they’ve ever made. Although ARC has since branched out a fair bit, they built their reputation on tubed amps, preamps, and integrated amplifiers.
This Integrated Amplifier drives my Wilson Audio Sophia 3 with ease. Paired with Transparent Super Cables and interconnects, this system is a force to reckon with.
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 “clipping” 80 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) 12Hz to 70kHz.
(-3dB points at 1 watt) 1.0Hz to 70 kHz.
0.55V RMS Single-ended for rated output. (32.5dB gain into 8 ohms.)
52.5K ohms Single-ended.
(5) 1, 2, 3, 4, 5 (Single Ended RCA connectors).
10V RMS (any input).
Non-Inverting (any input).
Volume up, Volume down (103 steps), Power, Input, Mute, Bias. All functions on IR remote control.
Approximately 2dB 8 ohm load to open circuit (Damping factor approximately 4).
8 ohms, 4 ohms.
OVERALL NEGATIVE FEEDBACK
