Product Description

The ALLO DigiOne is simply the most advanced digital (S/PDIF) transporter for Raspberry PI. There isn’t much more to say about this, really.

The DigiOne is expensive when compared to similar solution, but it’s definitely worth every penny of it. What we have here is something that was not designed to sound good, but to sound as best as possible (on Raspberry PI), and this is not yet another case of over-engineering: they made clear design choices which my listening impressions confirm to be correct.

To me, the DigiOne (or DigiOne Player, if you look for a complete player) are the best choice possible as of now if you own an S/PDIF DAC, or if you know for sure that the implementation of S/PDIF receiver in your DAC is superior than the USB side.

UPDATE: On sale is version 1.2 of Digione, which has very important improvements:

  • Improved ground sensitivity (rock solid with any DAC and AMP including ones with relays)

  • Small improvement on jitter

What they did, was develop the best possible Digital Transport HAT for the Raspberry PI, and let the measurements talk:

Jitter value = 411.4 femtoseconds 


  • BNC and RCA (coaxial) connector
  • Galvanic Isolation
  • Jitter as low as 0.411ps (1 picosecond – time taken by light in a vacuum to travel approximately 0.30 mm)
  • Noise as low as 50uV
  • 10 LDOs
  • Based on WM8805
  • 2 NDK oscillators
  • Master SPDIF configuration
  • Compatible only with Raspberry PI 2 and 3 (not Sparky)

    What about DAC grounding?
    Other digi boards with galvanic isolation on coaxial output need a grounded dac unit, otherwise there could be playback problems… Same case here?
    Thanks a lot
