MOONRIVER AUDIO - Inspirat de un cantec celebru, brandul Suedez este o combinatie
inedita intre design vintage si clasic, contemporan.

Produse placute ochiului cu un sunet organic, natural, cu un dinamism fara efort si o spatialitate
care da o savoare inegalabila la acest pret.

Capacitate iesita din comun in conducerea unor boxe cu mult peste pretul lor (al amplificatoarelor).

Fiabilitate si modularitate care se gasesc, in mod normal, la categorii mult mai ridicate de pret.

The 404 integrated amplifier

Moonriver Model 404 is the outcome of a 3-year research, the aim being to achieve incredible
performance regardless of price range.
The 404 amplifier will extract hidden elements and render textures from within any audio format,
with the source, speakers and room to set the limits.
Its culture will suit all music, as the Model 404 is by design set to define the faintest nuances of
which tone integrity is composed.

A hefty supply section ensures that ample healthy power is available at all times at all stages through
separate rails.
A fully discrete preamp section serves for acute dynamic awareness, while a high output stage that is
custom-optimized for bandwidth and distortion warrants for neutral predisposition and transient fidelity.
A laborious selection of components armors the design against tonal alteration, pretentious or not,
thus preserving naturalness throughout the shortest feasible path.

Furthermore, an integrated phono stage, a USB DAC, two preamp outputs and a tape monitor loop
expand functionality to form an ideally flexible integrated amplifier.

Design & Ergonomics

We had a very clear vision when we conceived the Moonriver 404 amplifier:
Classic design with a modern touch; high quality materials such as massive aluminum knobs,
solid walnut cheeks, sturdy enclosure; ergonomic user interface.

There are no “shaved” aesthetics here, no display with complicated serial menus and hidden functions,
nor a single multi-function knob for “minimalistic” purposes.

The heart of 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.

Modular Architecture

Moonriver 404 amplifier is modular by nature; it can accommodate an MM or MM/MC phono stage and
a USB asynchronous DAC.
Fitting these modules is simple and can take place at any time, on or after purchase.
The USB DAC may also be upgraded with a newer version to meet future needs.

Balance Control

You may find this feature to be vanishingly scarce in audiophile products as a result of today’s “minimalist”
design mentality and the various myths accompanying it.
However, balance control addresses a common problem; speakers that are positioned in asymmetry,
in a non-balanced room environment.
It thus provides the simplest tweak towards achieving a proper sound stage.

Living rooms and house furniture are meant to serve everyday life and may not be provisioned
with an ideal listening spot, evenly distanced from each speaker to form an equilateral triangle.
It is also not uncommon for one speaker to have to be placed nearer room boundaries than the other,
having various frequencies boosted in a more or less predictable pattern.
More often than not, balance control would come in handy in that it drastically helps overcoming volume
level unevenness and in some cases even reclaiming stereo effect and the resulting focused sound stage.

As expected, the way balance control is implemented on the Moonriver 404 amplifier, in parallel, will not
degrade or affect the signal in any way determinable.

Discovering the layout

Model 404 incorporates no less than 5 separate power supplies, each featuring overload protection.
The power amplifier specifically runs on a dual mono configuration, beginning from separate windings
on the toroidal transformer.

Signal switches are implemented via relays, while volume attenuation is trusted on the legendary blue ALPS pot.

A soft start circuit based on a 30A relay ensures that even the on/off switch is thought out to work with virtually
no burden or wear for decades.

Components are carefully selected for both suitability and reliability.
We make no use of surface-mount in analog circuits, despite the fact that through-hole costs more and requires
advanced space management & layout strategies.

Each element utilized has to be of proven stability and sustained higher performance - proficient implementation
provided- before making it into our analog paths.

As for the sound, we are not to say whether Model 404 is virtually transparent or inherently forgiving.
Voicing it to appreciate the playlist and respect the user at all times has been the sum of all of our effort;
a sincere effort to achieve effortlessness.

The Importance of Tape Monitor Loop

Probably most of today’s manufacturers reject the idea of their product featuring a tape loop.
At Moonriver Audio, we have concluded that the tape monitor loop is essential.
Not only does it add the option of monitoring the difference between recorded and source material at
a real time.

It also, and most importantly, makes possible to insert to the chain - at will - a digital or analog room
correction processor, a buffer, a noise reduction system or any other line device available to improve
the sound of connected sources.

Stereo/Mono Switch

The pristine era of analog recording being long gone, features like the stereo/mono switch have been
gradually chased out into obsolescence.
Who wants to go back to one when they have two channels?
“Less is more” and “more is better”.
Well…

As vinyl record revamping climaxes, whether a modern rage, a fashion thing or a real movement, countless
monaural pressings emerge out there, often along with their digital… image.
Too many of them, among others waiting to be rediscovered, have currently become collector’s items, 78 rpm
direct-cut gems being no exception.
This is not unreasonable, as what happened between say the 30s and the 80s in terms of both musical interpretation
and recording technique is by many considered to be “most of the music” - this sentence doing perhaps no justice to
stunning actual developments in creation and reproduction.
Stereo/mono switch gives you the chance to enjoy recording art milestones with respect to how they were initially
intended to please; in genuine mono, 2-channel, doing away with artificial phase discrepancies induced by mandatory
stereo mode.

So, “less” may well be “more”, but better is to have a choice.

Optional Phono Stage

Model 404 comes with two options in the phono stage department; one is MM only and the other is MM/MC selectable.
Both follow the exact quality principles that Model 404 is built on.
Quality components and massive power supplies are also employed here, to efficiently accommodate very low noise,
high performance op-amps.

The gain in the MM/MC phono can be adjusted, simply by changing the dip switches position.
The MC input load can be set also, by replacing the original 100 Ohm input resistor with a higher or lower value.
No soldering is required.

Optional USB DAC

What was desired for our USB DAC module was not to make an addition rather than an omission; instead we had
to be confident of substantially raising the true value and functionality of Model 404.
