Hello Community,
after working a few days with the wonderful roon software, using the Aries mini as endpoint, i stumbled over the Digione Signature reviews of John Darko and Hans Beekhuyzen. Because i wanted to upgrade my endpoint shortly, i thought i will give the Digione Signature a try.
With my electronic skills and years of active working in the diyaudio.com community, i agree with the concept to power the Digione Signature with a clean power supply.
Especially the recommendation to use LiFePo4 batteries to push the sound quality, coincides with my experiences at my Red Baron DAC project, a NOS TDA1541A DAC, in the past. In this project i tried different LiFePo4 batteries and one stands out, the A123 Systems ANR26650M1B.
This battery gave the best sound reproduction in my DIY-DAC project and for me, the best LiFePo4 in this case.
With this in mind, i ordered a custom made Battery-Pack at my favorite Online Store Lipopower.de.
Because we need at least 5V for the clean side and i would like to have 5.000 mAh capacity, i ordered the Battery-Pack with 4 ANR26650M1B. Two connected in series to get 6.6V and the other two connected parallel, to get the double capacity. This has also the effect, that it lowers the internal impedance. Low impedance of the batteries is highly regarded.
The whole pack also ordered with the correct connectors for the charger comes within 2 days.
As you could see on the picture, i ordered an additional cable for balanced charging. Thats important for long time stability of the LiFePo4 batteries.
For charging i ordered the SKYRC S60. A good and cheap charger.
The last thing thats needed is an adapter from the XT60 plug on the Battery-Pack to USB-Female. Unfortunately i found non “ready to use”, so i must do it myself. A very easy job. Only four things needed:
- XT60 Female plug from Lipopower.de
- Delock Adapter USB 3.0 Type-A female to Terminal Block 10 pin
- short 0.75mm cable
- shrinking tube
This power solution is not to pricy:
- Custom made Battery-Pack with 4 A123 Systems ANR26650M1B LiFePo4 and balance charging cable, Ready To Use - € 92,10
- XT60 Female plug - € 2,25
- Delock Adapter USB 3.0 Type-A female to Terminal Block 10 pin - € 7,99
- SKYRC S60 Charger - € 39,90
Total: € 142,24
Now charging starts…
…connected to the Digione Signature…
…and from there to my Chord Dave.
The result is outstanding!
I have my rig over years now, but never heard that clarity with so much depth and such a wide room.
What can i say… A big thank you to @allo.com for this great product!!!
Best regards,
Oliver

A more elegant version of my LiFePo4 adapter.
