Moonriver Audio

Handcrafted in Sweden

Moonriver Audio builds hand-assembled amplifiers and phono stages in Malmö, Sweden — fusing vintage Japanese aesthetics with modern Scandinavian engineering to create electronics that sound startlingly lifelike.

Philosophy

We employ every technology available today without staying dogmatically exclusive to one design principle versus another — be it solid state, integrated circuit, or vacuum tube. What matters is that the technology fits the application. Our goal is not to impress with specifications, but to move the listener. Every component is chosen through extensive listening tests, and every product is hand-assembled using through-hole construction for decades of reliable service.

Products

Integrated Amplifiers

Class A/B integrated amplifiers with modular upgrade paths.

Phono Stages

Hybrid phono preamplifiers for the dedicated vinyl listener.

Technologies

The innovations that make Moonriver Audio products extraordinary.

Through-Hole Construction

Built to last. Built to be serviced.

Every Moonriver product uses through-hole components in its analog circuits — hand-soldered onto PCBs designed for the shortest possible signal paths. This traditional construction method is more labour-intensive than surface-mount, but it produces more robust joints, is easier to inspect and service, and allows components to be replaced individually decades from now.

Surface-mount technology dominates modern electronics for cost and density reasons, but Moonriver deliberately chose a different path. Through-hole components have larger solder joints that resist fatigue and thermal cycling. The PCB layouts are optimised for minimal trace length rather than maximum component density, keeping the signal path as short as physically possible. Tool-free lid removal means any qualified technician can inspect and maintain the amplifier without special equipment.

Hybrid Topology

The right technology for each stage.

Moonriver combines integrated circuits, discrete solid-state, and — where appropriate — valve circuits in a single product. Rather than adhering to a single design ideology, each gain stage uses whichever topology sounds best and measures best for that specific application.

In the 505 phono stage, IC op-amps handle initial amplification where their vanishingly low noise floor matters most, while a discrete high-current output stage provides the body and dynamic slam that only discrete circuits deliver. In the 404 Reference, National Semiconductor LM3886-derived output devices are paired with a fully discrete preamp for the most natural, uncoloured presentation. This pragmatic, technology-agnostic approach is central to the Moonriver sound — warm and organic like valves, yet controlled and dynamic like the best solid-state.
