about moonriver audio
Moonriver Audio is a Swedish electronics maker founded by George Polychronidis, who worked as a hi-fi service technician in Sweden before designing the company's first product. The brand came from an industrial-design and repair background, and that shows in its core idea: an integrated amplifier built as a set of swappable modules, so an owner can add a phono stage, DAC, or other functions over time rather than replacing the whole unit. The line is anchored by the Model 404 integrated amplifier and the upgraded 404 Reference, both modestly powered Class A/B designs (the Reference rated around 50 watts per channel into 8 ohms) built by hand in Malmo. The modular card slots are the defining feature — the same chassis can be specified as a bare line-stage integrated or filled out with optional source boards. Moonriver competes in the boutique-integrated conversation with makers like Hegel, Rega's Aethos, and the other small-batch European amplifier houses — buyers weigh the upgrade-over-time argument and Swedish build against more powerful or more featured rivals. In the US it is distributed by Philip O'Hanlon's On A Higher Note and also sold through Music Direct. Press coverage is strong for an import this size: a Stereophile review with measurements, plus coverage in Hi-Fi News, hi-fi+, Wall of Sound, and ecoustics. Every unit is handbuilt in Malmo, Sweden.
