Allo DIGIONE Player Streamer SPDIF Output Double relocking of The Digital S/PDIF Transporter Outstanding Sound Quality with BNC Audio Output Compatibility: RPI only

Awesome sound as advertised ! Raspberry Pi is getting a bit toasty now, as I had to remove the top of my case that has a fan built in. Looking for a case that will fit both RPi 4 & Allo Digi One HAT that has a side mounted fan. Anyway great product

Very easy to install on an rpi 3b+, and I have it set up as a Roon endpoint. The sound quality easily blows away my Bluesound Node 2, which will now go on eBay. I highly recommend the DigiOne.

I read and watched John Darkos posts on how to create a Squeezebox server and player with Raspberry Pi and a HAT. The DigiOne HAT is expensive, but probably the best one available. Ive found the sound to be pristine, and my FLAC files sound just as good as if I played from my CD player.

...with one of these and a Pi you have a first rate music transport. Im using Volumio with actually recognises that Im using two such devices in my household and I can use an old phone as my remote. The Allo is the key to an excellent player. When these became unavailable, possibly because of Covid, I used another high end brand with equally good results. Review elsewhere on Amazon.

This item is pretty good for what it offers. You would need to buy a Raspberry Pi 3B+ (not 4B), a linear power supply for Raspberry, and a micro SD card in addition to this HAT board. The total cost of this project is around $260 with all items included. Now the sound: The DigiOne + LPSU is actually very good. It actually better than the Blue Sound node 2i which is offered for twice the price on Amazon. The DigiOne + LPSU is about 90% of the MicroRendu (not the Ultra version). Keep in mind that I also use a LPSU with the MicroRendu for the comparison. The wireless option can be used for the DigiOne, but it will significantly reduce the SQ. So, I suggest that you only use Ethernet connection. Using Bluetooth with the DigiOne also significantly reduce the SQ. Instead, you can use Apple AirPlay as a better alternative solution. The total time it takes for me to assemble the DigiOne is around 2 hours: 30 minutes to install the HAT and case. 1 hour for software installation (I use Moode in this case) 30 minutes for SqueezeLite and Airplay configuration. I almost cannot tell the difference between the DigiOne and the MicroRendu at the beginning ... and with careful back and forth comparison, I found that the MicroRendus sound is a little bit more relaxing and more revealing than the DigiOne. But, the difference is not much at all, and I have a very expensive and revealing audio system. My conclusion is: this product is pretty decent for its price.

Love the sound.

Its amazing how the sound can improve when you upgrade your RPI with an ALLO Hat. Noticeable improvement all around, but specially on his and mids. Thanks to the guys from IOT Electronics for a great service and attention to detail.

Outstanding sound quality; 3D, clean and lifelike ! Used with a Pi 4.
