The Reference 80S is a stereo power amplifier from Audio Research, built with a substantial input impedance and an exceptionally wide bandwidth. The Reference 80S brings Audio Research's most storied engineering heritage to dedicated stereo power amplification.
Key specs that matter
Input impedance is a substantial 300,000 ohms balanced or 75,000 ohms single-ended. Output power is 70W into 8 ohms. Frequency response spans an exceptionally wide 0.7Hz to 94,000Hz within plus-or-minus 3dB. At 482.6 x 260 x 470mm and 28.2kg, the Reference 80S represents a substantial power amplifier 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 0.7Hz-94kHz bandwidth providing comprehensive frequency coverage.
Pairing
Audio Research's own preamplifier catalogue offers natural, brand-coherent pairings for a coherently voiced, entirely Audio Research-based system.
Alternatives
Audio Research's own VT80 SE offers a monoblock alternative within the same broader catalogue for buyers preferring separate mono chassis.
