It's built by hand in Malmö, with five completely separate power supplies and through-hole rather than surface-mounted components in the analogue section – effort you rarely find at this price.\u003c\/p\u003e\n\u003ch2\u003eWhy the Moonriver 404?\u003c\/h2\u003e\n\u003cp\u003eBecause it shows that understatement works in amplifier design too: a plain black front with walnut side cheeks, four large aluminium knobs, three switches – done. Behind that sits a fully discrete preamp circuit in dual-mono layout, each channel half with its own power supply and its own overload protection. The balance control and the stereo\/mono switch are details that turntable fans know to appreciate – not every integrated amp in this price class still offers that.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cp\u003eFive inputs, including slots for an optional phono module (MM or MM\/MC) and an optional SPDIF or USB DAC module – so you only retrofit what you actually need, instead of paying for a factory fit-out that gathers dust on the shelf. Plus a tape loop for anyone still recording to analogue, two pre-outs for a later expansion with an active subwoofer or an external power amp, and a recording output.\u003c\/p\u003e\n\u003ch3\u003eWho is the 404 suited for – and who isn't it for?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eStraight talk:\u003c\/strong\u003e the 404 is for anyone who wants an honest, unfussy amplifier without streaming ballast, and who values the freedom to retrofit phono or a DAC only when needed. If you expect network streaming built into the device from day one, the 404 isn't for you – that needs a separate streamer or a different model. And if your demands on the preamp stage are already at the top end, take a look at the 404 Reference straight away: more power-supply capacity, same housing, noticeably more reserves.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eAn integrated amplifier that doesn't show off with features but wins you over with clean execution – exactly the understatement that built its reputation in the specialist press. \"Here was an amplifier that suited these values perfectly, by opening a compelling window onto your music\" – Chris Thomas, hi-fi+, June 2021. If you value modular expansion over factory fit-out, it's one of the most honest choices in its price class.\u003c\/p\u003e\n\u003ch2\u003eTechnical data – Moonriver 404\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e integrated amplifier with fully discrete preamp circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier principle:\u003c\/strong\u003e dual-mono power-amp layout, 5 independent power supplies, each with its own overload protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput power:\u003c\/strong\u003e 2 × 50 W at 8 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency range:\u003c\/strong\u003e 10 Hz – 50 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistortion (THD):\u003c\/strong\u003e 0.05%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-to-noise ratio:\u003c\/strong\u003e 85 dB (line)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 5 analogue inputs incl. tape loop, including slots for an optional phono and USB DAC module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 2× pre-out, 1× recording out\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e 4 aluminium knobs, 3 switches, balance control, stereo\/mono switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e steel chassis with solid walnut side cheeks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandby power draw:\u003c\/strong\u003e 22 watts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptionally retrofittable:\u003c\/strong\u003e phono module MM or MM\/MC, SPDIF or USB DAC module (only one digital module at a time)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W×H×D):\u003c\/strong\u003e 43 × 13.5 × 39 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 12 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e handmade in Malmö, Sweden\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 3 years (manufacturer)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eCan I add a phono input to the Moonriver 404 later?\u003c\/h3\u003e\n\u003cp\u003eYes. The 404 has free slots from the factory for a phono module (MM or MM\/MC) and a digital module. Both can be retrofitted at any time without having to buy a new unit – our technician will fit it for you.\u003c\/p\u003e\n\u003ch3\u003eHow does the 404 differ from the 404 Reference?\u003c\/h3\u003e\n\u003cp\u003eBoth share the same housing, power and circuit concept. The Reference version brings significantly more power-supply capacity, which mainly benefits dynamics and detail resolution. If you want maximum reserves, go for the Reference.\u003c\/p\u003e\n\u003ch3\u003eCan I retrofit USB and SPDIF DAC at the same time?\u003c\/h3\u003e\n\u003cp\u003eNo, there's only one slot for a digital module. You choose USB (computer\/streamer via USB) or SPDIF (classic digital source) – both can't be fitted at the same time.\u003c\/p\u003e\n\u003ch3\u003eDoes the 404 need a subwoofer connection?\u003c\/h3\u003e\n\u003cp\u003eIt doesn't have a dedicated subwoofer output, but it does have two pre-outs. An active subwoofer with a line input can still be integrated cleanly through those – just ask us, we'll show you how.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the Moonriver 404 from HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause we show you which module actually suits your system before you pay for it – and take care of the fitting ourselves if needed.
