What Sbooster does
Sbooster is a Netherlands-based specialty electronics company founded in 2010 by Wiebren Draaijer and Karin Hoks, focused on designing and manufacturing audiophile-grade linear power supply upgrades. The company addresses a specific pain point in high-end audio systems: standard switch-mode power adapters leak noise and interference into signals, degrading sound quality. Sbooster's product portfolio centers on the BOTW P&P ECO MKII linear DC power supplies (covering 5V to 24V across 6 models and 16 interchangeable DC plugs), the BOTW AC power supply for AC-driven devices like phono stages and turntables, the Ultra MKII active add-on filter, and OEM-specific upgrades such as the Bluesound Node Active Interface Board and Lumin Connection Kits. The underlying technology combines a 4-stage purification process (dual-stage mains filter with Earth Line Choke, audio-grade toroidal transformer with electrostatic and HF magnetic shielding, Schottky rectification with low-ESR capacitors, and a proprietary Split-Current System) to achieve sub-1mV ripple, 25mV voltage accuracy, and >80dB ripple reduction on the Ultra MKII.
Sbooster operates a vertically integrated model: design is led from the Netherlands while manufacturing is conducted at the company's own production facility in Bulgaria. The go-to-market is purely indirect, relying on a global network of regional distributors (Harmonia in the USA, Saturn Audio in Canada, DREI H in Germany/Austria, Symphony Distribution in the UK from January 2026, L'Audiodistribution in France, Penhold in Benelux, MadForMusic in Italy, MIC Audio in Greater China, Norman Audio in Southeast Asia) and a long tail of authorized dealers spanning 25+ countries. Pricing is not publicly listed and varies by region, with products sold as one-time hardware purchases. Revenue is generated exclusively through hardware sales, with no recurring software or service component. Marketing relies on earned media through audiophile publications (Positive Feedback, Hifi Pig, HI-FI Choice, Hifi.nl, Alpha Audio, The Ear, HifiStatement), YouTube reviewers (Hans Beekhuyzen, Alpha Audio, Upscale Audio's Kevin Deal), trade show participation (CanJam Europe 2017), and technical white papers.
The company has remained entirely bootstrapped and founder-owned since inception, with no external investment, no parent company, and no M&A activity disclosed. Compatibility has been a deliberate strategic pillar: Sbooster maintains a published compatibility list covering hundreds of devices across premium audio brands (Bluesound, Mytek, Lumin, WiiM, Roon, Musical Fidelity, Chord, Auralic, Melco, Rega, Thorens, ELAC, Fluance, Dual), positioning its products as de facto standard upgrades within the audiophile aftermarket. Certifications include CE plus TÜV Rheinland and KTL safety approvals, with a 24-month warranty offered across the product line.

Sbooster competitors and assessment
Company assessmentEmerging players
- Paul Hynes Design: Ireland-based boutique builder of high-end custom linear power supplies for audio. Directly comparable niche: small, design-led LPS maker targeting demanding audiophiles with custom-regulated outputs.
- KEMP HiFi Power Supplies: Specialty builder of linear power supplies for high-end audio (formerly ToneAudio). Directly comparable niche player focused on bespoke audiophile LPS solutions in a similar price/performance band.
- Wyred 4 Sound: US-based audio brand with a power-conditioning and amplifier line aimed at the audiophile/music-server market. Comparable as a smaller specialist competing in upgrade-class mains and audio components.
Others
- Chord Electronics: UK high-end DAC/amplifier/hugo maker listed by Sbooster as a compatible device customer (Hugo TT2, M-Scaler, Qutest). Adjacent peer: a premium OEM whose product roadmap directly affects Sbooster's upgrade-tam addressable base.
- Rega Research: UK turntable manufacturer whose stock AC/AC power supplies are commonly replaced by Sbooster's BOTW AC. Adjacent peer: a turntable OEM and customer whose installed base drives Sbooster's PSU upgrade demand.
Direct peers
- IsoTek: UK-based specialist in mains conditioning and power cables for hi-fi and home cinema. Sells through a similar global distributor/dealer channel and addresses the same 'noise from mains' problem Sbooster targets, though at a broader power-conditioning level.
- Puritan Audio Laboratories: UK-based manufacturer of mains conditioners, power cables, and power distributors for audio/video systems. Competes for the same audiophile and high-end AV customers looking to clean up AC mains going into streaming and DAC equipment.
- iFi Audio: UK-based audio accessories brand (part of the AMR/Abbingdon group) selling mains-powered linear supplies (iPower, iPower Elite) directly comparable to Sbooster's BOTW P&P ECO line. Targets the same streamer/DAC/turntable upgrade market with transparent retail pricing.
Broad incumbents
- PS Audio: Long-established US audio brand with a deep power-management line (PowerPlants, regenerators, conditioners) plus amplifiers and DACs. Comparable as a higher-tier incumbent in the audiophile mains-power category, with broader product breadth than Sbooster.
- Nordost: US manufacturer of high-end audio cables and power products (Qbase, Sort Kone, power cords). Comparable as an established specialist in the broader 'clean signal/power' chain that audiophile customers also purchase.
