Jedno od najuspješnijih integriranih pojačala posljednjih desetak godina dolazi iz tvrtke Moonriver audio. Model 404 predstavljen je svijetu u više od desetak recenzija renomiranih audio časopisa. Svi sa neskrivenim oduševljenjem navode izuzetnu kvalitetu zvuka, ali i jedinstveni vrlo dopadljiv retro dizajn, kao i odličnu izradu. Model 404 modularne je konstrukcije, može se isporučiti sa internim gramofonskim pretpojačalom uz doplatu od 700 eura. Reference verzija konstruirana je za najzahtjevnije audiofile.
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.
Furthermore, an integrated phono stage, USB DAC, (two) preamp outputs and a tape monitor loop expand functionality to form an ideally flexible integrated amplifier.
We had a very clear vision when conceiving the Model 404 Reference amplifier: Classic design with a modern touch; high-quality materials such as over-sized aluminum controls, solid walnut cheeks, sturdy chassis and an ergonomic user interface.
There are no ‘for show’ aesthetics here, no display with complicated serial menus and hidden functions, nor a single multi-function knob for ‘minimalistic’ purposes.
The heart of the Model 404 is pure and minimal, but the interface is user-oriented and easy to operate by anyone in seconds, with no need to resort to the user manual. Four knobs and three switches give direct access to any function.
