The timing is favorable here: this is an older-generation add-on supply rather than a current flagship, so the key question is value, and at £63 it lands well below the £106 25th percentile and far under the £179 median of your recent GBP comps. That makes it a strong bargain rather than just a fair price.
These Sbooster supplies are generally sought after for lowering noise and giving DACs, streamers, and other 5V gear a cleaner, more stable feed than a stock wall wart. If the seller can confirm the exact output spec, connector, and that it’s the right 5V version for your kit, this looks like an easy buy at the money, especially since the listing is already in the cheap end of the market and there’s no obvious reason to wait for a better one.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sbooster, a Dutch specialist in audio upgrade power supplies, traces its roots to 2008 when founder Wiebren Draaijer launched it under the name Squeeze-upgrade. Designed and developed in the Netherlands, the brand emerged from Draaijer's work enhancing Logitech Squeezebox players, evolving into a focused enterprise dedicated to plug-and-play solutions for hi-fi components.
The company concentrates exclusively on linear power supplies, such as the acclaimed BOTW (Best of Two Worlds) series, including the P&P ECO MKII models. These upgrades target network music players, headphone amplifiers, DACs, and other devices reliant on external PSUs, delivering cleaner power, reduced electrical noise, and superior current stability to elevate audio performance without altering the host equipment.
Positioned as a niche boutique in the high-end market, Sbooster earns praise for reliability, award-winning consistency since its 2018 MKII lineup, and tangible sonic improvements at accessible prices from its Bulgarian production. Reviews spanning 2010 to 2025 highlight its enduring value as a long-term system essential, backed by exceptional customer care, appealing to discerning audiophiles seeking precision upgrades over flashy marketing.
