Powerman™
High Current Linear Power Supply for Formula S

Powerman™ was originally developed as an upgrade companion for the XIAUDIO™ Formula S headphone amplifier, Powerman™ is a dedicated external power supply engineered to unlock the amplifier’s full sonic potential.

By replacing the internal power source with a high-current discrete linear supply, Powerman™ provides greater energy reserve, lower noise, and improved stability — allowing Formula S to deliver a more refined and immersive listening experience.

More Power. More Space. More Musicality.

At the heart of Powerman™ is a low-noise discrete regulation circuit paired with a large toroidal transformer, delivering a cleaner and more stable power foundation for the Formula S amplifier.

The result is a deeper soundstage, enhanced micro-detail retrieval, improved spatial realism, and a quieter background that lets music emerge with greater clarity and natural expression.

Installation Note

Before connecting Powerman™ to Formula S, disconnect AC power from both units.

Formula S must never be connected directly to AC power while connected to Powerman™, as this may cause damage.
