Sbooster BOTW P&P MKII High-Quality Power Supply Upgrade


Is your product compatible?

Most probably! Below are quick links to the TESTED products. Don't fret if your product is not on there--if it uses an outboard power supply (junky wall warts etc.) it'll probably have a matching Sbooster. Details further in on how to evaluate a unit not on the list.

The audiophile power supply solution

Power is everything. Some of the biggest improvements, outside of getting that expensive component upgrade you've been eyeing, come from upgrading the electrical power supply to your system. Whether it's upgraded cables, a power conditioner, or better individual PSUs for components, the jump in detail, bass extension, air, and dynamics are electrifying. These are accompanied by notable drops in grain, noise floor, and a general fog around the sound that you didn't even know was there until it went away.

The Sbooster Best of Two Worlds Power & Precision Mk II is a highly optimized, heavily shielded linear power supply with noise filtration. Available in multiple voltages, Sboosters are compatible with a wide variety of components. Now you can boost the performance of everything from a network switch to an Intel NUC to a Lumin streaming DAC to a Dr. Feikert Woodpecker turntable, and more. The improvement is often two-fold: not only do you give your chosen component a supply of clean, dynamic power, you take a switching power supply out of your system. This is especially true of network and computer components, which often come with a cheap & nasty PSU that injects high-frequency switching noise into the mains supply. This "wall wart" can pollute the sound of your entire system, not just the product it is connected to.

The Sbooster BOTW P&P Mk II has new features that improve power flow, reduce mechanical stress, and lower internal impedance over the original.


  • High-quality PCB with double sided 2oz. copper, and a gold-plated finish
  • Better and thicker heatsink from the previous model
  • Upgraded internal wiring with high-quality silver plated copper and PTFE insulation
  • Heavy transformer with electrostatic shielding and HF magnetic shielding
  • Upgraded bulk capacitors
  • Improved reference-circuit
  • Next generation split-current unit
  • New DC-output cable with additional shielding, sleeve and gold plated connector pins
  • Custom-made DC-plugs

Voltage Identification and Compatibility

Sbooster Power Supplies come in six different models. If your component isn't listed on the compatibility list where the voltage is specified, you need to look at the back of your component. Locate the DC input on your component. Nearly always, the voltage will be specified.

Sbooster has a compatibility list of products they have tested. Note, if your product isn't on the list, it doesn't mean it won't work--you just have to look in detail at the voltage and current requirements.
