Audio Research VM220 Monoblock Power Amplifier, Black finish, Pre-Owned

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.

Specifications

• Power output: 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. e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
• Input sensitivity: 1.8V RMS Single-ended or balanced for rated output. (26.7 dB gain into 8 ohms.)
• Input impedance: 100K ohms Single-ended, 200K ohms balanced differential.
• Output taps: 4, 8 ohms
• Output regulation: Approximately 0.8 dB 8 ohm load to open circuit.
• Overall negative feedback: 14dB
• Damping factor: Approximately 12
• Distortion: -
• Slew rate: 25V/µs
• Rise time: 1.5 µs
• Hum & noise: Less than 0.2mV RMS - 106dB below rated output (IHF weighted, input shorted).
• Power supply energy storage: Approximately 332 joules
• Power requirements: 105-125VAC 60Hz (210-250VAC 50Hz) 620 watts at rated output, 900 watts maximum, 400 watts at "idle".
• Tube complement: (4 matched pairs) 6550C power output, (4) 6N1P input and driver
• Other: Balanced and singled ended inputs, switch selected. 12V input/output connections for remote start-up installations. 12 gauge detachable line cord, 20 amp. IEC connector.
• Dimensions: 17½" (44.5 cm) W x 7.9" (20.1 cm) H x 19" (48.3 cm) D. Rear connectors extend .88" beyond chassis.
• Weight: 54.7 lbs. (24.9 kg) Net; 63 lbs. (28.6 kg) Shipping.
