Replacing a switch mode power supply

Most small audio components arrive with a switching wall adaptor chosen for cost and size rather than noise performance. Replacing it with a linear or low noise supply is one of the more reliably audible upgrades available to a streaming system, particularly where the component's own internal regulation is modest.

Three specifications have to match. Voltage must be exactly what the equipment expects. Current capacity must equal or exceed the original supply, and more is not a problem. Polarity is usually centre positive but not always, and getting it wrong can damage the equipment, so check the label on the original adaptor before ordering.

The router and network switch feeding a streamer are also running on switching supplies, and upgrading those is sometimes more effective than upgrading the streamer's own. Send us the model and a photo of the original adaptor label and we will confirm the correct specification before you buy.

Sbooster power supplies provide clean, stable current to your audio and video devices. By eliminating electrical noise and voltage fluctuations, they improve dynamics, reduce distortion, and create a more natural, engaging performance.

Dedicated power supplies or upgraded DC supplies are most commonly used with low-voltage digital equipment such as streamers, DACs, routers, and network switches. These components are particularly sensitive to electrical noise from standard switch-mode power supplies.

Upgrading the DC supply can improve timing, clarity, and background quietness. These upgrades tend to be most effective once the core system is already well balanced and you are aiming for refinement rather than a dramatic tonal change.
