Is €300 a fair price for this used Sbooster BOTW? At €300, the asking price sits clearly above the 75th percentile of €268 and the median of €231, making it ambitious compared to typical used market values in EUR. While a new unit often costs around €300, paying that for a used item offers little upside unless the condition is pristine and accessories are complete.
However, the Sbooster BOTW is a well-regarded linear power supply that significantly reduces ripple and mechanical stress, delivering cleaner power to expensive audio gear. Its stable regulation and low internal impedance make it a worthwhile upgrade over standard wall-warts, especially if bought in excellent condition with original cables. If the listing truly reflects pristine, original-owner quality, it becomes a credible buying opportunity despite the price.
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.
