Hello Maudifi, interestingly I'm also using with great pleasure such an Allo USBridge + DigiOne Signature combination inside of the metallic box from Allo (*). The clean "audio" part is supplied by two 18560 batteries in series (with another separate 18560 couple recharged in the meantime), autonomy is much more than 20 listening hours and I just lift slightly one of the two batteries letting it in place to save battery load when the streamer is not playing. I mounted a small digital Voltmeter connected with a push button to control the 18560 pair voltage and use them unless it decreases below to the 7V limit when the streamer is playing (roughly 50% load). (*) DigiOne Signature"s BNC output preferred to USBridge's integrated clean USB output - but this depends also from the DAC and its ability to treat S/PDIF vs USB But FYI I even use pure battery power for the main USBridge "dirty" main supply part because I felt that even this one affects the music quality : for this I apply a 12V 20Ah sealed battery connected to a motorcycle battery charger that can be left connected permanently. I use a good 5Vdc regulator to supply the USBridge, followed by a 1 mF super-capacitor . When I'm listening seriously I just disconnect the charger from mains with a RF remote control device. Autonomy is 12 hours and more. Here I have a digital voltmeter permanently connected to the battery and try to avoid decreasing below 12,3V (nominal is 12,6V). For me the main drawback of these battery supplies is to not forget to manage their reload after the listening session (especially the more critical 12V one). But once you get used to it, it is easily manageable. In comparison to audiophile mains power supply I'm convinced the value for money is (much) better ! Greetings for your videos, I'm eagerly waiting for the next one :-) Audiophile regards from France ! Stéphane
Bonjour Stéphane, merci pour vos commentaires et votre partage d'expérience. I may look into battery supply for the USBridge at a later date. I completely agree, the autonomy is good with the 18650 battery pack. This Allo combination with the batteries represents fantastic value. Interestingly, as alluded to in the video, I did consider integrating battery management (integrated charging) into this project, but decided to leave it for another time. Too many projects, not enough time :-). I hope to get the next video out soon. Cordialement, Scott
Hi Scott - I just came across your channel. I like what you are. trying to do, upscaling audio for the individual, and your approach. I have been using Digital All streamers for a few years now. I started with the DigiBoss DAC on a Raspberry PI, then added a DigiOne on a RPi3, and lastly a separate USBridge Signature Player with a linear power supply. The DigiOne and USBridge I use on 2 separate systems. I am trying to understand the benefit of combining a DigiOne signature and USBridge. Is it the ability to output via Coax/BNC or is there a benefit in performance? Thanks!
Hi John, thanks very much for your support. In the same way that the main benefit of the DigiOne Signature is reduced noise transfer from the Pi, I think the same applies with the USBridge when using the DigiOne Signature. All those separate regulators for the different board functions can only help keep noise further away from the audio related parts. TBH though, I haven't tried any other options. I've been happy so far with what I have. The main reason I bought the USBridge was for future flexibility to have a good USB DAC connection too.
Very interesting because I have a usbridge sig and I am contemplating getting a digi one sig - I will follow with continued interest! One thing I have found very useful with the usbridge is the addition of a flirc IR receiver (no affiliation!) in one of the front USB ports - enables me to use my remote control to do play, pause, skip etc and I use this all the time.
What I would find extremely exciting would be for you to publish a parts list with links for your finalized build. This way, some of the more intrepid of us can purchase and build.
Many thanks for your enthusiasm. It is very encouraging. In short, watch this space :-), but meanwhile... Check this out: maudifi.co.uk/the-sigi If there is enough interest I plan to produce a kit for the Sigi enclosure and will definitely have links for Allo boards, and sundry components. You can register your interest here: maudifi.co.uk/the-sigi/sigi-register-your-interest
@@maudifi all signed up. Currently have a Auralic Femto with SBooster hooked up to a Holo Audio May KTE DAC. Always looking to experiment and try something new. I think your kit idea is inspired and you seem to have the technical expertise to make something worth having which has true value added. Kits are great as they also allow for a personalized aspect to the music experience.
@@jblesser Thanks, that's great! I try. I agree, it's amazing what we can discover and there is always great satisfaction in building something that sounds great yourself. Not to mention the value for money.
Yes, you could. There are many possibilities. I chose to keep this project simple initially, but may return to it to add the bells and whistles in the future.
One option I am considering is using the PI2AES transport with the Allo USBridge Signature. This would ensure the RPI player is as clean as possible before handing off the a transport that can provide both I2S and AES along with SPDIF and optical outputs. What do you think? Is this a worthwhile line to pursue? Most DACs today have I2S inputs something the DigiOne Signature does not offer. Allo also makes a low noise dual power supply called Shanti.
I'm sorry, I don't have experience with the Pi2AES so can't comment. In principle, that sounds like a good plan though to lower the noise floor. Yes, most more modern DACs do have a greater variety of interfaces. In my case I only required S/PDIF and USB, so haven't investigated beyond that yet. You just have to choose the one that most suits you while providing a low noise output. You may want to look at Gabster's streamer build at th-cam.com/video/jR0VBHwxQ8o/w-d-xo.html. This uses the Allo USBridge with other PCBs from @IanCanadaTT.
@@maudifi thanks. I did consider Ian Canada’s product but once you add the cards the cost was exceeding $600. The USBridge and PI2AES would cost half that.
Thanks for uploading! If you have a second, I've been recording some original acoustic songs. As a fellow music lover, I'd love if you'd take a listen. It's on my page. Hope you like it.

Couldn't you just make a power switch that toggles between battery going TO the pi when ON. And make it disconnect the battery and charge it when off?

helloo ,thank you... i have allo L.K.S audio dac 003 . what are your thoughts
Thanks for your interest in my video. I'm sorry I don't know the LKS device so can't comment.
Could you run it off batteries and make the raspberry pi control the charging of the batteries when its not in use?
Yes, you could. There are many possibilities. I chose to keep this project simple initially, but may return to it to add the bells and whistles in the future.
