Lineo5 has an aluminum chassis with heatsinks along its sides.

What it does

Cleaner power for 5 V gear

Lineo5 takes the place of the external switching power supply that runs your streamer or DAC. Its linear design gives your system clean, stable 5 V power.

An illustration in two halves. On the left, labelled Switching PSU, a wavy line. On the right, labelled Linear PSU, a straight, steady band.

A switching supply and a linear supply.

A linear supply

A linear power supply holds a large reservoir of clean, stable power and keeps electrical noise low. Power delivery stays consistent, so you hear more of the detail and the transients in your music.

Less ripple and interference

Lineo5 uses linear regulation, and its filtering reduces ripple and interference on the 5 V output. The residual noise is 20 µV.

A toroidal transformer

A toroidal transformer sits at the heart of Lineo5. It feeds a single 5 V output with up to 5 A.

Audio-grade capacitors

Lineo5 uses audio-grade, low-ESR capacitors with 40,000 µF of bulk capacitance, a large reservoir of power for the moments your system needs it most.

Aluminum, cooled passively

A simple, honest design. The chassis is aluminum, a robust and non-magnetic material, and the heatsinks along its sides cool the electronics passively.

  • 110 or 220 V

    A switch on the back sets the mains input: 110–120 V at 60 Hz, or 220–240 V at 50 Hz.

  • An easy-to-reach fuse

    A fuse protects Lineo5, and it is easy to reach.

  • For 5 V audio gear

    Stable, clean power for high-end DACs, headphone amplifiers and network streamers that run on 5 V.

Other 5 V gear

  • Lineo5Check your device

Lineo5 is made for 5 V audio gear. Its output gives 5 V DC, tip positive, through a cord that ends in a 5.5 × 2.1 mm barrel jack, with up to 5 A. Compare that with your device’s power input.

Lineo5 or Lineo5 Duo

Both are linear 5 V supplies with a toroidal transformer, in the same 27.1 × 22.7 × 7 cm aluminum chassis, and they work with the same devices. Lineo5 has one output with up to 5 A. Lineo5 Duo has two independent outputs with up to 4 A each, so one supply can power two devices.
