The Cyrus Audio 40 Amplifier is most certainly one of the most competent and highly spec’d Integrated amplifiers that I have had here for review. It really is the Swiss Army knife of amplifiers, being able to do it all and do it all so well, no matter what the source is, it is not fussed delivering music with all the musicality and energy that I have known and loved from the Cyrus Audio brand for so many years now.
