  • Audio Research VS110

    Audio Research VS110

    Audio Research VS110 2 available price is for each unused since 2014 in 11/2021 Given the enthusiastic response to the appearance and sonic peformance of the VS55, you will be happy to know that a more powerful version of this remarkable amplifier is now available: the VS110, rated at 100 WPC. This brings vacuum-tube musicality as only Audio Research can do it to a new power level and price. The chassis, circuit layout and feature set of the VS110 are almost identical to the VS55, but scaled up to accomodate the greater power output. The chassis itself measures 17 ½" W by 19" D, and features an anodized, natural-finish top plate labeled with tube location/type, output-tube bias access points and the inset Audio Research logo. The chassis front holds a rocker-style power switch and green LED "on" indicator. The chassis rear provides the 0-4-8 ohm 5-way binding posts, voltmeter test points for setting bias, a 12V in/out trigger and a detachable 14-gauge A.C. line cord with IEC socket. There are two matched pair of 6550C output tubes in each channel, fed by two 6NIP triode driver/followers, which in turn are fed by a single 6NIP input tube. Storage capacity of the bulk power supply is double that of the VS55 and uses the same type of fast, low-ESR Nichicon® capacitors. The simplicity and purity of the audio circuit is a proven performer, but now it can deliver more power for larger speakers in larger rooms. Like the VS55, the VS110 ships in one color /chassis configuration, black with natural anodized top plate. A perforated cage-type cover is optional, and must be ordered as a separate item. The sonic signature of the VS110 is very much like that of the VS55, but with more robust dynamics, greater bass impact and power, and a larger soundstage. With so much similarity between these two amplifiers, choosing the right amplifier is simple. The look, the feature set, the circuit types are identical: it is simply a question of how much power you need or want. The VS110 combines classic tube-amplifier appeal with robust power, genuine musicality and solid value. And don't forget Audio Research's unmatched record for long-term product support - a key measure of keeping customers satisfied, decade after decade. POWER OUTPUT 100 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 100 watts, below .05% at 1 watt. Approximate actual power available at "clipping": 120 watts (1kHz) (Note that the actual RMS power output is dependent upon both line voltage and "condition" ie: 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) 10Hz to 40kHz FREQUENCY RESPONSE (-3dB points at 1 watt) 0.8 Hz to 40 kHz INPUT SENSITIVITY 1.1V RMS Single-ended for rated output.
