Swedish Moonriver Audio are proud to announce a new model, the 404 Reference integrated amplifier which is the improved version of the Standard model. Following the runaway success of The Moonriver Model 404 (Standard) the Reference version moves further, by improving on the already excellent design platform of the Standard 404 model. The form, controls, ergonomics and design are similar, but the major difference is found at the heart of the amplifier: the power supplies.
The 404 standard uses a total of 57,000uf capacitance. The 404 Reference lifts the capacitance to a spectacular 107,000uf of which 21,000 of them are reserved for the preamp only. This enormous increment expands the driving behaviour; the dynamic character; digs out more detail; low level information; a deeper and more articulate soundtstage; space between instruments is vast, while the bass has greater authority and is more confident than ever before.
The texture of each individual instrument is exposed exponentially in comparison with the Standard version. A fully discrete preamp section serves to provide acute dynamic awareness, while a high output stage that is custom-optimised for bandwidth and distortion, gives neutral character and transient fidelity. A sophisticated selection of components fuses the design against tonal traits, therefore preserving naturalness throughout the shortest feasible signal path.
3-year manufacturer warranty included. Available with an MM or an MM/MC phono stage. A D/A Converter option being developed shortly as well.
