The Cyrus One is an integrated amplifier that provides 40 W RMS power. This 2-channel model is fitted with phono MM/MC input. Circa 1986
Amplifier is in very good cosmetic condition, see photos. In full working order.
Designed by Cyrus to handle demands of modern loudspeakers and wide bandwidth recordings, the Cyrus One featured an exceptional power supply capable of responding to the source material requirements. This is the heart of the amplifier, the source of its stress free sound.
To keep the signal as pure as possible, the Cyrus One features ‘minimalist’ circuitry devoid of the non-essential stages which interrupt the signal path. The signal integrity is preserved, even through this short path, by the use of only the finest components, including military grade power transistors and selected passive elements.
The cabinet and chassis are designed to do more than just elegantly cover the Cyrus interior: the case itself is made from a precision diecast non-ferrous metal alloy, while the chassis with integral heatsink made of diecast aluminium. In addition to structural integrity not demonstrated by any other amplifier at or near the Cyrus price range, these features improve the sonic fidelity by dispelling mechanical resonances, circuit microphony and airbourne radio frequency interference.
"Are Cyrus amplifiers good? Once thoroughly warmed-up, the Cyrus Two puts in an astonishingly good performance for something made over 30 years ago. It sounds clean, crisp and immensely detailed"
