Прочие устройства — SOtM sPS-500

The sPS-500 is a linear power supply from SOtM, built specifically for high-performance audio applications where SOtM believes a power supply should never be considered just a power supply unit - the resolution, textures, transparency and overall expression of sound reproduced by any audio system is directly affected by how and what power feeds it. Designed to eliminate noise generated by connected devices as well as noise arriving from the AC mains itself, the sPS-500 uses SOtM's own proprietary noise-cancellation and sound-enhancement technologies alongside high-quality components already proven elsewhere in the brand's product line.

Key specs that matter

AC power input accepts a wide 100-240Vac range at 50/60Hz, drawing 1.6A. DC output voltage is selectable across 7Vdc, 9Vdc, 12Vdc or 19Vdc to match a specific connected device's power requirement, with voltage tolerance held to plus-or-minus 10%. Current limit is 5A at 7V, 9V or 12V, dropping to 3.3A at 19V, also with plus-or-minus 10% tolerance. Maximum output power varies with mains voltage - 55W at 120Vac, 50W at 110Vac and 45W at 100Vac - flexible enough to power NAS units, fanless audio PCs, network switches and numerous other DC-powered audio components. Protection circuitry covers both output short-circuit and over-temperature conditions, with input, output and overcurrent protection contributing to stable power delivery regardless of connected load. The user interface is deliberately minimal - a DC output on/off switch, a single operating-indicator LED, and a rear-panel AC power input switch. Higher-tier SE variants add further refinements - the SE-S-Evox configuration uses a stranded silver Y DC cable with additional EMI shielding, silver internal wiring and Evox capacitors, while the SE-C-Evox variant substitutes stranded copper wiring and DC cable for a different sonic balance at a lower price point.

Sound and use context

Expect rich texture and a detailed, luxurious sound quality that creates a fresh listening experience with whatever it powers - one owner specifically described the sPS-500 as by far the best linear power supply used on a media streamer, calling the improvement unbelievable and praising both the build quality and the high-grade DC cable supplied with the connector.

Pairing

The selectable 7-19Vdc output range and 45-55W capacity cover a wide range of DC-powered devices directly, and SOtM's own network switches, servers and clock generators specifically benefit from the sPS-500's noise-reduced power delivery when substituted for a stock switching-mode supply.

Alternatives

SOtM's own sPS-1000 sits above this model as a considerably higher-capacity linear supply for buyers with more demanding power requirements, worth the further investment if this sPS-500's 45-55W maximum output ceiling falls short of what a specific audio component or combination of components requires.
