What customers say
The SOtM sPS-500 Power Supply is celebrated by audiophiles for delivering transformative sonic improvements, primarily through its ultra-low noise performance. Users consistently note a significantly blacker background, which enhances clarity, micro-dynamics, and instrument separation across the soundstage. The build quality is regarded as premium and robust, justifying its specialized nature. While the performance gains are deemed essential for maximizing digital source quality, the high cost remains the main point of discussion regarding overall value compared to less expensive alternatives. For serious enthusiasts focused on peak digital audio performance, this unit is considered a critical, high-impact investment that elevates the entire system.
Know before you buy
The sPS-500 is designed for high-performance audio components that require a clean, stable DC power source. Because it offers selectable output voltages of 7V, 9V, 12V, and 19V, it is compatible with a wide range of DACs, streamers, and network switches that operate within those specific voltage requirements.
The sPS-500 utilizes advanced noise cancellation technology to filter out electrical interference from your AC power source. By providing a cleaner, more stable power delivery, it helps reduce the noise floor, which typically results in improved audio resolution, better transparency, and a more refined soundstage.
Yes, the unit features a selectable voltage switch on the back, allowing you to toggle between 7V, 9V, 12V, and 19V. Always verify the specific voltage and polarity requirements of your device before connecting it to ensure compatibility and prevent damage.
The sPS-500 is equipped with comprehensive protection circuits, including over-temperature, short-circuit, and overcurrent protection. These safeguards are designed to automatically protect both the power supply and your connected audio equipment in the event of an electrical fault.
No, the sPS-500 is designed with a fanless, silent architecture. It relies on its chassis design for heat dissipation, so it is recommended to place the unit in a well-ventilated area away from other heat-generating components to ensure optimal performance.
The dedicated DC output switch allows you to safely toggle the power to your connected device without having to unplug the unit from the wall. This is particularly useful for power-cycling your equipment or turning off your system when it is not in use.
