This month’s MagPi magazine includes a review of the Allo DigiOne Player, a clever though high-priced add-on for the Raspberry Pi which its creator claims gives it pitch-perfect digital audio capabilities.
Designed as a ‘digital transport’ – a device which provides a digital, rather than analogue, signal for decoding by an external digital-to-analogue converter (DAC) – the DigiOne Player is a plug-and-play design based on Allo’s DigiOne S/PDIF HAT. As the name suggests, the primary part of the Player is a Hardware Attached on Top (HAT) add-on for the Raspberry Pi which provides a Sony/Philips Digital Interface (S/PDIF) audio output on an RCA or BNC jack; the Player is simply a bundle which includes a Pi, case, and cabling.
There’s no denying that the DigiOne is a clever design, with a surprising amount of hardware crammed into a small space. At nearly £150, though, it’s priced head and shoulders above the competition and lacks some of their features – such as the optical output of the £30 JustBoom Digi HAT, ditched due to what Allo calls unacceptable built-in jitter levels avoided through the use of electrical connectivity.
For my conclusion on the device’s value, you can pick up The MagPi Issue 67 at your nearest supermarket, newsagent, or for free download under a Creative Commons licence via the official website.
