Säljer 1 st Sbooster 18-19 volt med 1st Purple säkring kostar enbart 1.700 på special pris. Tillsammans 3.500 kr, utan säkring 2.700 kr. helt i nyskick.
Sbooster power supplies sit in that “small box, real improvement” category, especially for streamers and DACs that respond well to cleaner power. At kr 3,500, this sits above the kr 2,784 75th percentile and well over the kr 2,469 median, so it reads as ambitious rather than a bargain.
The appeal is straightforward: these units are usually bought to tighten up noise floor, focus, and overall ease without changing the character of the system, and a unit with the Synergistic Purple Fuse suggests the seller has already invested in upgrades. That only makes sense if the accessory package is complete and the unit is in genuinely clean condition; otherwise, the premium is hard to justify versus the broader used market.
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.
