I'm selling this only because I changed systems, as part of the constant curiosity about what else is 'out there'. I purchased everything brand new back in August of 2020, and only used it a handful of times over the span of less than a year. This means that everything is basically 'new', and the batteries have only been cycled around 10 times. Also of note, I built this very carefully, even using white gloves to avoid getting fingerprints on the PCBs or inside of the case. I have decades of experience working with computers and electronics as well.

The Raspberry PI4 is the 2gb version. The included A123 18650 LiFePo4 batteries are regarded as the most reliable and best quality. These are also reported by many, including Allo, to give the best sound when powering the Digione Signature. As can be seen in the pictures, I wired the battery holder with an inline toggle switch, which makes it much easier to turn the system on and off. Without this, one would have to just unplug the USB-C cable every time, which I thought was a bit crude.

Also included is a 5ft BlueJeans BNC cable. The other cable pictured is a microUSB with bare ends for powering the RPI4 with something that has screw terminals. I used an Astron linear power supply with the exact voltage needed, for example (but this isn't included in the sale). Additionally I'm including the Samsung 32gb Pro Endurance MicroSD card, which I've freshly formatted, ready for any operating system of choice. The only thing needed from the new user is a power supply for the RPI4 (even the stock wall-wart would do fine), and a charger for the batteries (make sure it supports LiFePo4).

This is a beautiful sounding endpoint, and I cannot say that anything I've heard has been objectively 'better'.

I can ship to US and Canada, and local pickup is available in the Syracuse or Montreal area.

Thanks for looking, and feel free to ask any further questions.
