Carte allo digione signature - essais et comparatifs

[steklo]

Salut Alain,

je suis Stefan de Berlin. Mon français est trop mal, permettez-moi de continuer en anglais...

As far as I understand, you prefer to use this powerbank for the cean side of Digione signature:

As this powerbank has two outles, one rated @1A the other one @ 2A, have you tried to power both the clean side (1A) and the dirty side (2A) from the powerbank at the same time? This would be quite interesting for me as I am about to buy a Ciunas ISO-PS for exactly the same purpose:

This PSU has two outlets too, both connected to one battery inside.


BUT: With one battery feeding both sides of Digione signature these two sides share the same ground and that is counterproductive with respect to the galvanic isolation implemented into Digione signature and thus might degrade soundquality.
On the other hand ultra clean battery power fed to RPi might improve soundquality. Question is, how the outcome really is when feeding both sides from one battery vs. feeding the clean side from battery and the dirty side from something else.

I would be glad if you could check this. Unfortunaltely Ciunas' summer sale (-25%) ends tomorrow so it would be simply wonderful if you report back soon - in case you find the time.

Best regards and thanks a lot
Stefan
