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, as the Lineo5 Duo shop page illustrates them.

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

Linear regulation and filtering reduce ripple and interference. In Lineo5 Duo, each output has its own regulators and filtering, and the residual noise is 20 µV.

A toroidal transformer

A toroidal transformer sits at the heart of both models. In Lineo5 Duo it delivers the power each output needs with a wide margin, so it never comes close to its limits, even in the most demanding listening sessions.

Audio-grade capacitors

Lineo5 uses premium transformers, capacitors and voltage regulators, for reliable performance and durability. Lineo5 Duo 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 both models, 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.
