AI-assisted summary

Description from the seller

Specifications
Output power: 40 watts per channel into 8Ω (stereo)
Frequency response: 20 Hz to 20 kHz
Total harmonic distortion: 0.1%
Damping factor: 20
Input sensitivity: 2.7 mV (microphone), 2.7 mV (MM), 230 mV (ceramic), 100 mV (line)
Signal-to-noise ratio: 65 dB (MM), 75 dB (line)
Output: 155 mV (line)
Speaker load impedance: 4Ω to 16Ω

A very well-built amplifier. Great phono input. Bass and treble correction for each speaker separately. Being able to adjust the input volume is also an advantage. They sound very good and precise in the mid and high ranges, with bass that is dynamic and accurate. Despite its size, it also delivers impressive performance.
The sound is clear and warm, as one would expect from a Revox of that era.
