The Heart of Your High-End Audio System

Power, precision, and efficiency in perfect harmony. The Best of Two Worlds Power & Precision ECO MKII is the definitive linear power supply upgrade for the demanding audiophile.

Pure Energy for Unmatched Performance

Many audio devices come with a low-cost switch-mode power adapter (SMPS). While functional, these adapters are often a major source of high-frequency noise and interference that directly pollute your audio signal.

The Sbooster BOTW P&P ECO MKII tackles this problem at the source. By replacing that weak link with a pure, stable power source, you lift the "veil" from your music. The result is not just better sound, but a completely new listening experience: deeper silences, a wider soundstage, and a natural timbre that you simply have to hear to believe.

Perfecting the Audio Chain

Every audiophile knows that an audio system is a chain of components: from router to streamer, from DAC to amplifier. But the most critical link—the one that drives them all—is often overlooked: the Power Supply.

To enhance your Audio Chain, we engineered a dedicated external power supply solution. The purification process starts immediately where the polluted mains power enters the power supply and doesn't stop until pure DC power reaches your equipment.

The 4 Stages of Purification:

Stage 1: The Input Filter - The Shield The purification starts at the very first contact point. Before the current even reaches the transformer, our Dual-Stage Mains Filter with Earth Line Choke acts as a barrier, eliminating high-frequency pollution from the power grid instantly.

Stage 2: The Transformation - The Heart The clean power is then passed to the Audio Grade Toroidal Transformer. Electro-statically and HF-magnetically shielded, this custom-made heart ensures that the conversion from AC mains to low voltage AC happens without adding any hum or noise.

Stage 3: The Conditioning - The Foundation The low voltage AC is then rectified to DC using ultra-fast Schottky diodes to minimize switching noise. This power is stored in a bank of Low ESR bulk capacitors, creating a massive energy reserve for dynamic response. A precision shunt reference circuit with high performance regulator then locks the voltage in place, ensuring rock-solid stability before the power leaves the enclosure.

Stage 4: The Split-Current System - The Flow Finally, at the end of the chain, as close as possible to the audio device, lies our unique innovation: The Split-Current System. This system divides the power flow: one path creates a massive buffer for speed and dynamics, while the other filters the voltage and current one last time.

Uncompromising Build Quality   

The BOTW P&P ECO MKII wasn't just designed for sound; it was designed to last.

Since its introduction, this power supply has established itself as the global benchmark for reliability and consistency. We don't believe in cutting corners.

Every unit is assembled with precision in our own European facility, using only the best components to ensure decades of musical enjoyment.

  • Premium Materials: From the double-sided, gold-plated PCB to the high-grade polypropylene film capacitors, every internal component is selected for maximum stability and longevity.

  • Superior Wiring: Internally, we use high-quality silver-plated copper wiring with robust PTFE insulation. This ensures a durable, oxidation-free signal path that maintains its integrity over time.

  • Heavy-Duty Design: The robust construction minimizes mechanical stress and internal resistance. This is not a disposable accessory; it is a serious audio component built to perform year after year.

World-Ready Performance

Sbooster power supplies are designed for global consistency. Whether you are in Tokyo (100V), New York (120V), or Berlin (230V), the performance remains uncompromising.

The power supply is factory set to match the official mains voltage specification of your country (100/110/115/120/220/230/240VAC)*. This ensures that the power supply always operates at its optimal efficiency and delivering a stable and silent foundation for your music, wherever you are.

In case you move to another mains voltage area, we are happy to assist you with adjusting the power supply according to the new mains voltage.

*Note: 127VAC is not supported.

System Flexibility             

The BOTW P&P ECO series utilizes a smart design to cover 11 output voltages with just 6 distinct models. This ensures there is a Sbooster power supply solution for almost any audio device.

  • Adjustable Power: Every model allows you to switch between three specific voltage settings to match your equipment perfectly (with the exception of the fixed 24V edition).

  • Universal Connection: The unit comes with our proprietary interchangeable DC-tip system, guaranteeing a firm and reliable connection regardless of the input type.
