The AETHOS is an accomplished integrated amplifier from Rega, built with a wide bandwidth and low distortion. The AETHOS brings Rega's considered engineering to a substantial integrated chassis.
Key specs that matter
Four single-ended inputs are provided. Input sensitivity is 224mV, with input impedance at 17,000 ohms. Output power is 125W into 8 ohms. Gain is 31.6dBu. Frequency response spans a wide 10Hz to 30,000Hz within plus-or-minus 3dB. Total harmonic distortion plus noise is 0.007%. At 433 x 95 x 360mm and 17.5kg, the AETHOS represents a substantial integrated amplifier commitment reflecting Rega's considered British engineering standards.
Sound and use context
Expect the accurate, considered character Rega's broader British catalogue is celebrated for, with the wide 10Hz-30kHz bandwidth combined with the low 0.007% distortion figure.
Pairing
Rega's own source and loudspeaker catalogue offers natural, brand-coherent pairings within the same broader catalogue.
Alternatives
Rega's own ELICIT MK5 offers a more accessible alternative within the same broader integrated amplifier catalogue.
