Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support. Somewhat rare mono amps from ARC (no others were found for sale at the time of posting this), capable of delivering a conservative 200W into just about any load. Fitted with lightly used and tightly matched 6550 tubes. Perfectly biased and ready for years of enjoyment.
Tested in both our lab and our listening area to ensure you receive a perfectly working amp pair. Also includes a pair of very nice 20A to 15A IEC power cords converters. SkyFi Testing Notes: Tested all output tubes including spares.

Installed tubes, Biased to 65mV (65mA) Each Bench tested each amp to rated power with equal clipping characteristics Sweep Test Pass Listening Test Pass More From ARC: The VS 55 and 110 power amplifiers have been instrumental in bringing new customers to Audio Research - customers who are looking for exceptional sound and the look of a classic vacuum-tube amplifier. In 2003, we began receiving requests for a monoblock power amplifier similar to the VS series, with more power and a reasonable price. We are proud to annouce the VM220 monoblock power amplifier, which represents the capstone of this series, offering performance and features that go well beyond its companion products in the VS series.
Output is conservatively rated at 200+ watts. While similar in size and appearance to the VS110, the VM220 uses an additional 6N1P front-end tube. Its purpose is to provide the differential signal for true balanced operation, a first for this series. With both balanced and single-ended inputs (switch selected), the VM220 will be compatible with every Audio Research preamplifier. In addition, the VM220 uses a super-wide-bandwidth output transformer to provide better frequency extension, explosive musical dynamics, and more powerful bass extension and speed.The VM220 has classic tube sound virtues, but with greater extension, air and a robust bass response that goes far beyond anything you have heard from the VS series before. Like all our amplifiers, the VM220 offers 12V input/output connections for remote start-up installations, and a heavy-duty 12 gauge detachable line cord with 20-amp IEC connector. Output taps are 0-4-8 ohms.
The VM220 also had a hot-start lock-out feature which prevents the amplifier from being restarted too quickly in the event of inadvertent shutdown or power failure - thereby preventing undue stress to the output tubes. The VM220 is sure to become another classic design from Audio Research. 200 watts per channel continuous from 20Hz to 20kHz.1kHz total harmonic distortion typically 0.5% at 200 watts, below 0.05% at 1 watt. Approximate actual power available at "clipping"; 230 watts (1kHz). Note that actual RMS 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) 10Hz to 100kHz. (-3dB points at 1 watt) 1.0 Hz to 140 kHz. 1.8V RMS Single-ended or balanced for rated output.
26.7 dB gain into 8 ohms. 100K ohms Single-ended, 200K ohms balanced differential. Approximately 0.8 dB 8 ohm load to open circuit. Less than 0.2mV RMS - 106dB below rated output (IHF weighted, input shorted).
105-125VAC 60Hz (210-250VAC 50Hz) 620 watts at rated output, 900 watts maximum, 400 watts at "idle". (4 matched pairs) 6550C power output, (4) 6N1P input and driver.
Balanced and singled ended inputs, switch selected. 12V input/output connections for remote start-up installations. 12 gauge detachable line cord, 20 amp. 17½" (44.5 cm) W x 7.9" (20.1 cm) H x 19 (48.3 cm) D. If we dont have the original manufactures packaging, we use heavy duty double-ply corrugated boxes with custom made to your item Instapak expanding foam custom inserts.
In many cases this has proven to be better than the original packaging! We also use high quality fiber reinforced tape to seal our packages.We have too many items for sale and its nearly impossible to keep track of offers outside of the official system. We accept trade-ins of equal or lesser value under certain conditions. Please visit our website to submit your gear for full consideration. We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. And will typically pass on displays, projectors, receivers, dated surround processors, and mid-fi equipment of any type. We will offer a fair value for your equipment, but keep in mind were running a business and will need to be able to resell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning, and packaging the incoming equipment. SELL US YOUR GEAR (Working or Broken). Simply visit our website to submit your gear for full consideration. We are currently operating from our shop inside our dedicated building in Glen Rock, NJ. We have several well-equipped and dedicated listening areas, plus a dedicated listening studio with tons of equipment of all makes and models. Were not a store, so please dont make an appointment if youre just curious as to how a speaker or piece of equipment sounds. In essence - no tire kickers please. This is super useful when purchasing large speakers or heavy amplifiers. Its also great for ensuring your new turntable is setup correctly in its final resting place. Yes - Power and Adapters.
