The Mission Cyrus One Mk1 is a legendary British integrated amplifier launched in late 1984 by Cyrus Audio (then a division of Mission Loudspeakers). It is celebrated for its minimalist design, compact "shoebox" footprint, and high-fidelity sound that defined the golden era of British hi-fi. 

high spec built-in MM / MC switchable phono pre-amp, here is one of the best British integrated amplifiers ever made. This one is the much more desirable Mk8 version, with heavy cast metal chassis and high quality front fascia (with headphone socket) - as opposed to the earlier plastic cased versions.
