The 404 Reference integrated amplifier
Following the
runaway success of The Moonriver Model 404 (Standard), we decided to
move a step further by improving on the already excellent design
platform of the Standard 404 model. The Moonriver Model 404 Reference
achieves even better performance over the Standard Model, while
retaining a sensible price point.
Just like the Standard Model
404, the 404 Reference amplifier will extract hidden elements, and
render textures from within any audio format; but with the capability to
drive any speaker on the market – despite its moderate power. Only the
source, speakers and room will set the performance limit. Its culture
will suit all music, as the Model 404 is by design, set to define the
faintest nuances of which tonal integrity is composed.
The power
supply section has been improved to the maximum. The 404 standard uses a
total of 57000uf capacitance. The 404 Reference lifts the capacitance
to a spectacular 107000uf of which 21000 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.
