Sign up for our newsletter. Audio Research VSi55 Vaccum Tube Integrated Amplifier - 6550 - 6N1P.Integrated vacuum tube amplifier from Audio Research - the VSi55. 50 watts of power per. Into 8 ohms using a pair of 6550 vacuum tubes in each channel. Tubes test good and strong for many more hours of musical enjoyment. This unit is in very good cosmetic condition with just a small blemish on the side of the chassis. It works perfectly and comes with the remote control and power cord. All of the pre-owned items that we sell are thoroughly inspected and tested both on our test bench and in our listening room. 50 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 50 watts, below. 05% at 0.1 watt. Approximate actual power available at clipping 52 watts (1kHz).
Note that actual power output is dependent upon both line voltage and condition i. 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 90kHz. (-3dB points at 1 watt) 1.0 Hz to 100 kHz. 0.5V RMS Single-ended for rated output.
(32 dB gain into 8 ohms). Approximately 1.5 dB 8 ohm load to open circuit. Less than 0.14mV RMS - 103dB below rated output (IHF weighted, input shorted).100-125VAC 60Hz (200-250VAC 50Hz) 320 watts at rated output, 500 watts maximum, 205 watts at "idle". 0.5 watts power off. (2 matched pairs) 6550EH power output, (3) 6N1P input and driver. Inputs: CD, Tuner, Video, SE1, SE2 (Single Ended RCA connectors). Maximum input: 3.5V RMS (any input).
Optional 6dB pad for CD use. Output polarity: Non-inverting (any input). Push buttons: Volume up, Volume down. (70 steps, 20 LED indicators), Input, Mono, Mute, Power. All functions on IR remote control.
Mono subwoofer output: 1V RMS at rated power. Power supplies: Electronically regulated Low and High Voltage supplies for input stages. Automatic 30 second warm-up/brown-out mute, with the volume control reset to zero. 14" (35.6 cm) W x 8" (20.3 cm) H x 16(40.6 cm) D.(15.5 kg) Net; 40 lbs. The Primare exhibits a noticeably drier tone and lacks the bass command so apparent in the VSi55. Musically, the only edge in the Primares favor would be in terms of imaging, but even here the difference is slight. I prefer the Primares digital look and especially its precise volume control. When using multiple sources with an integrated amplifier, there are often variations in volume between them. With the Primare, it is very easy to remember that, say, a volume level of 50 is appropriate for one source but is ten points too high for another. Suitable adjustments can be made in advance of pumping out the sound. The imprecise volume indicator on the VSi55 was much more troublesome in this regard. Of course, the Primare is also a solid-state integrated amplifier.
I leave it powered on continuously. Doing so with the VSi55 would significantly reduce the life span of the tubes and increase the units overall cost of ownership.Ultimately this is a matter of personal preference. To the uninitiated, tubes may seem to possess a sense of fragility, with their typically low (on paper) power ratings and exposed glass organs. The Audio Research VSi55 is a strong argument against this impression.
Musically, the VSi55 does not exhibit any sense of weakness or an overly light touch. Put another way, the VSi55 can play Metallica -- loud. Yet its no brute either, and readily lends an open airiness to delicate material. Tubes dont last forever, and they can be hot and even marginally dangerous in an environment with bustling children, cats, ferrets, and the like, which means extra cost for the protective cage.
Some may not appreciate the basic aesthetic of the VSi55, and its user interface, while perhaps advanced for a tube-based component, is somewhat limited by todays digital standards. But taking everything into account, especially sonics, the Audio Research VSi55 is a distinguished performer in its price range and rightfully occupies an audition spot alongside elite integrated amplifiers.
