The Reference 160M MkII is an accomplished monoblock power amplifier from Audio Research, built with an exceptionally wide bandwidth and substantial input impedance. The Reference 160M MkII brings Audio Research's most storied engineering heritage to dedicated monoblock power amplification.
Key specs that matter
Input sensitivity is 2,400mV, with input impedance at a substantial 200,000 ohms balanced or 100,000 ohms single-ended. Output power is 140W into 8 ohms. Frequency response spans an exceptionally wide 0.5Hz to 110,000Hz within plus-or-minus 3dB. At 438 x 254 x 470mm and 25.5kg, the Reference 160M MkII represents a substantial monoblock commitment reflecting Audio Research's most storied engineering standards.
Sound and use context
Expect the accurate, richly detailed character Audio Research's broader storied American catalogue is celebrated for, with the exceptionally wide 0.5Hz-110kHz bandwidth providing comprehensive frequency coverage.
Pairing
As a monoblock, two units are needed for a stereo pair, and Audio Research's own preamplifier catalogue offers natural, brand-coherent pairings.
Alternatives
Audio Research's own VT80 SE offers a related tube-informed monoblock alternative within the same broader catalogue.
