Hi Luciano
What PSU are you using ? DSD to PCM click,thats independent of DigiOne its the way it was implemented in the DAC ic.
Hi Rik
Usualy what you describe can happen if there is noise on the ground. DigiOne is sensitive to any noise present in the grounds of the devices connected to the RCA/BNC .
What AMP is connected to your DAC ?
Can you send the logs ?
Hi @allo.com thanks for your reply.
Iām using a Ifi IPower 5V,
About the logs iāll send them ASAP
Thank you very much!
Ifi psu should be fineā¦however just for to make sure change the PSU (at least 2.5A)

On Monday I will have some news.
Interesting. I havenāt had this happen since Iāve changed the case that the RPi is in (if such a thing should make a difference). This was 2 days ago. I have it connected to a chord Mojo. Volumio is using WiFi.
Case should not make a differenceā¦however RPI wifi is not recommended for audio .I would suggest changing to a network connection or at least a better wifi dongle.

Completely agree ref: WiFi. Iām awaiting delivery of a 6m ethernet cable 
I previously had the Digione/volumio hooked up to my AV receiver and I had the problem there too. I will report back if the problem recurs.
I was using an ethernet cable connection and recently switched to a wifi dongle that sits at a distance and is connected using a simple 2 ā¬ 1. 5 meter USB extension cable. Connection is trouble free in my home and I cannot say I hear any difference in SQ. I could not run an ethernet cable through my living room and was previously using a power line network adapter which always had problems.

I installed the DigiOne on a Rpi3 running DietPi RoonBridge, powered by ifi iPower 5V, 48 hours ago. Compared to my Macās USB-connected Musical Fidelity V-LINK II, this board has a wider and more clearly defined soundstage, with more āairā, but lacks some of the solid bottom end that Iām accustomed to. Both are fed into coax SPDIF inputs on an all-digital Meridian surround system. The new Allo output is directly connected, while the USB chain uses Uptone and ifi conditioning.
Next, Iāll move my iPurifier to the DigiOne output and listen some more.
I agree the bottom end is lacking.
Is there any news on the alu case now?

Hi Brad, are you using the BNC connector or RCA output? When I purchased a new Coax cable from Audio Sensibility (The Statement SE) BNC to RCA, going BNC out made an additional jump up in performance. Also, powering the Pi and Allo Digi from a good linear supply made another noticeable jump up in performance - especially in the base department. If you want the best SPDIF out from this board you must use the BNC connector. My LPS is the
Thanks, Lou. I am using a Meridian RCA to RCA digital cable for an endpoint that has cost less than $200 total. Your top-of-the-line cable and PS suggestions would add another $700, so I wonder if there arenāt great sounding, but less expensive, alternatives.
Point taken, Iāve done a couple of tests back and forth to some of the other devices I have laying around:
- Micro Rendu with same UA Power supply and Wireworld Plat USB cable
- PS AUdio BRIDGE II
Initially this Allo DigiOne was for a cheap experiment, but the geek in me wanted to see how far I could take it. I currently think that IME the Allo Digi One via BNC Coax is the best sounding digital source. I am going to keep the Micro Rendu as I can use it in another systemā¦ The Coax just has a slightly more organic, and wider sound-stage.
fritzg - I see that we are both using iPower, and wonder if that has anything to do with bass performance.
