Sbooster BOTW P&P ECO MKII

The upgrade you don't hear about — until you hear it.

"Cleaner and stable power equals cleaner and stable music." — Positive Feedback

TONEAudio's Brutus Awards called the MKII update "a wonderful improvement" for the streaming gear they tested it with.

Most people spend their upgrade budget on speakers, DACs, and cables and completely ignore the little wall-wart power adapter plugged into their streamer or DAC. That's a mistake. Those stock adapters are cheap switching supplies, and they dump electrical noise straight into your audio signal — a low-level haze that dulls detail and flattens the soundstage without you ever quite knowing why.

Swap it for a Sbooster and you're not just adding power, you're subtracting noise. The result is a genuinely quieter background — deeper silences between notes — plus a soundstage that opens up wider and deeper than you'd expect from a power supply. It's the kind of upgrade that makes you go back and re-listen to albums you thought you already knew.

It's built to back that up: a shielded, audio-grade toroidal transformer, a two-stage filter that scrubs high-frequency noise before it even reaches the transformer, and premium internal wiring throughout. Three switchable voltage settings and a swappable DC-tip system mean one unit can cover a wide range of streamers, DACs, and network gear — so it's easy to match to whatever you're upgrading.

If your streamer, DAC, or network switch still runs off its stock adapter, this is the cheapest "new component" you'll ever buy that doesn't look like one.
