Sbooster BOTW P&P ECO Explained – The Simple Upgrade With Big Impact

FutureShop is an authorised dealer for Sbooster power supplies. The customer reviews quoted in this guide are from verified FutureShop purchases.

Our Verdict

The Sbooster BOTW P&P ECO is one of the most cost-effective and immediately audible upgrades available for any component powered by an external switch-mode adapter, delivering a lower noise floor, tighter bass, and greater musical clarity from the first moment of use. Adding the optional Ultra MKII module extends those gains further for Chord Qutest and other sensitive DAC owners.

Quick Take

  • Standard switch-mode adapters introduce electrical noise and voltage fluctuations into the signal chain. The BOTW P&P ECO replaces them with a linear power supply that delivers clean, stable current.
  • Reported improvements include a lower noise floor, tighter bass, cleaner treble, and a wider, more open soundstage. One verified customer reports 30% extra clarity and attack from first use.
  • Compatible with a wide range of DC-powered equipment: DACs such as the Chord Qutest, network streamers from Naim, headphone amplifiers, phono stages, routers, and network switches. Available in multiple voltage options.
  • The optional Ultra MKII module adds advanced filtering on top of the base unit, removing the last traces of harshness in the upper frequencies and tightening bass precision further.
  • Installation is plug-and-play: replace the existing wall adapter, and the improvement is immediate. No modification of the component is required.

When it comes to unlocking the full potential of your hi-fi or AV system, many enthusiasts focus on loudspeakers, amplifiers, and cables. Yet one of the most overlooked elements is also one of the most influential: the power supply. This is where the Sbooster BOTW P&P ECO makes a remarkable difference.

What Is the Sbooster BOTW P&P ECO?

The BOTW P&P ECO (Best of Two Worlds Power & Precision ECO) is a high-quality linear power supply designed to replace the noisy switch-mode adapters that typically come bundled with audio and video devices. By delivering clean, stable current, the BOTW P&P ECO helps your system perform at its very best.

Why Power Quality Matters

All electronic devices rely on the mains for their energy, but most standard adapters introduce electrical noise and voltage fluctuations into the chain. This noise can cloud detail, flatten dynamics, and cause listening fatigue. By contrast, the BOTW P&P ECO provides a silent, stable foundation, allowing your system's true character to shine through.

Key Benefits of the BOTW P&P ECO

  • Lower Noise Floor: Hear more subtle detail in your music.
  • Improved Dynamics: Tighter bass and a more expressive midrange.
  • Enhanced Clarity: Cleaner treble and a wider, more open soundstage.
  • Greater Musical Flow: A more natural, engaging listening experience.

Compatibility Across Devices

The BOTW P&P ECO is available in multiple voltage options, making it suitable for a wide range of equipment. Popular matches include DACs like the Chord Qutest, network streamers from Naim, headphone amplifiers, phono stages, and even routers or network switches. Wherever clean power is needed, the BOTW P&P ECO provides the upgrade.

Going Further with the Ultra MKII

For those seeking the ultimate refinement, the optional Sbooster Ultra MKII module can be added. This add-on delivers advanced filtering, lowering the noise floor even further and unlocking an extra layer of transparency and detail.

A Simple Upgrade, A Big Impact

Unlike changing speakers or amplifiers, upgrading to the Sbooster BOTW P&P ECO is straightforward and cost-effective. Simply replace your device's external adapter with the Sbooster, and the improvement is immediate and unmistakable. It's one of the simplest upgrades you can make, yet the impact on sound and vision is profound.

Choosing the Right Voltage and When to Add the Ultra MKII

The BOTW P&P ECO is available in a range of voltage variants (5V, 6V, 9V, 12V, 15V, and 24V among others), and selecting the correct voltage for your component is the most important step before ordering. Ordering the wrong voltage can damage the component: the BOTW's output voltage must match the voltage specified on the original wall adapter that came with the component.

How to find your component's correct voltage. The voltage requirement is printed on the original adapter next to the "Output" label, in a format such as "Output: DC 12V 1.5A". The voltage (V) figure is what you need to match. The current rating (A) of the BOTW must be equal to or greater than the original adapter's current rating: if the original supplies 1.5A at 12V, select a 12V BOTW rated at 1.5A or higher. If you no longer have the original adapter, the voltage is listed in the component's specification sheet, in the owner's manual, or on a label near the DC input socket on the component itself. If you are unsure, FutureShop's team will confirm the correct voltage and current rating before you order.

A note on the Chord Qutest specifically. The Chord Qutest is the most commonly asked-about Sbooster pairing at FutureShop and requires specific attention. The Qutest's standard adapter outputs 5V. The BOTW can supply either 5V or 6V. Sbooster's own guidance, confirmed by multiple customer and professional reviews, is that the Qutest performs slightly better when powered at 6V via the BOTW rather than 5V: Chord designed the Qutest to operate within a voltage range rather than at exactly 5V, and the slightly higher voltage produces a marginally more authoritative presentation. When adding the Ultra MKII module to a Qutest installation, set the BOTW output to 6V as the customer review above notes. FutureShop recommends confirming this against the most current Sbooster compatibility table, as both Chord and Sbooster occasionally update their guidance when firmware or hardware revisions are released.

Which component to upgrade first. The BOTW delivers the most audible improvement on components that currently use a basic switch-mode adapter and are sensitive to power supply noise in their signal path. In priority order: a DAC powered by a standard switch-mode adapter (the clock circuit is particularly sensitive to supply noise and the improvement in background silence and digital transients is consistently the most dramatic result reported by customers); a network router or ethernet switch in a streaming system (the noise that travels from the router's power supply through the ethernet cable into the streamer's network input is a commonly overlooked source of digital noise, and the customer review above from the Lumin U2 Mini owner illustrates this clearly); a headphone amplifier or phono stage powered by a wall adapter. The BOTW is not appropriate for components with internal mains-connected power supplies (amplifiers, most integrated amplifiers, and many streamer-amplifiers): these draw AC power directly from the mains and do not have an external DC adapter to replace.

When to add the Ultra MKII module. The Ultra MKII is a bolt-on module that adds a second stage of filtering after the BOTW's linear supply output. It is not a standalone product: it requires an existing BOTW to function. The Ultra MKII is most productive in components where the final traces of upper-frequency grain or bass looseness persist after fitting the base BOTW, and where the component's own internal regulation is of sufficiently high quality to reveal the Ultra MKII's additional refinement. The Chord Qutest is the most commonly cited example, as confirmed by the detailed customer review above: the BOTW removes the bulk of the noise, and the Ultra MKII addresses the residual harshness that the BOTW alone cannot eliminate. For components at mid-level or entry-level where the internal filtering is less resolving, the Ultra MKII's marginal improvement over the base BOTW is less audible. In these cases, the base BOTW alone is the more cost-effective choice.

Customer Reviews: Real-World Impressions

"Having tried the Sbooster 5v with my Chord Qutest, I found it made the sound of Qutest more refined, with blacker blacks and a less harsh top end. This Ultra MKII adds refinement even further. Any hint of harshness with the Qutest in the upper mids and highs is now absent, and the bass is tighter with more precision. Remember to set Sbooster to 6v when using this Ultra MKII add-on with Qutest as per the Sbooster website. This is an affordable tweak for Sbooster owners and well worth it for owners of Qutest and other DACs supplied with less-than-ideal SMPS wall wart power supplies. The Sbooster website has a compatibility table for DACs. Great accessory!"
"I use it with my Lumin U2 Mini feeding my UR Unico 90 amp. It's not a night-and-day improvement but nice cherry on top of the cake. The most obvious improvement is the better clarity, perhaps because of the better-controlled bass. Nothing can destroy the SQ more than the bass without the control or harsh treble. It fixed the loosened bass. Treble and mids stayed as good as they have been but slightly cleaner. Compared to the stock internal PSU, it's a better product, and if your system usually shows the changes in cabling, it will probably show the change with this PSU too."
"Straight out of the box this power supply shines! I would say it gives my system 30% extra clarity and attack."
