05 OSA electronics: DACBerry pro+
The DACBerry pro+ was last time better with a isolator.

May I ask how you connected this setup with the Thel NT-25HQ? I am considering going down that route as well for my DACberry PRO+ but I am not sure how I would connect the Thel LPS with the Rig (only power to the isolater or power to the isolater and the Raspi?)
Would also be interested how your Thel setup looks in general.

yes, i used the isolator board from OSA.
The Thel PSU is set to two independent 5,25V connections.
( i have the Thel EMI Filter installed too. http://www.thel-audioworld.de/module/Ne ... filter.htm EMI-306 )
In volumio using the OSA DACBerry ONE+ driver

With one NT-25HQ you have two clean and independent power connectors. (2x 1,4A)
I put two NT-25HQ in that case for more flexibility, and to share one EMI Filter, to save money.
I was thinking about the NT-50HQ but there is no need. same noise spec. etc.
I want to give every device in my contest a single, independent power rail, to keep away any noise from each other.
My next stepp would be Black pulsar BLP25-09 - http://www.thel-audioworld.de/module/Cl ... pulsar.htm
the disadvantage here is the heat and the continous consumption

I just ordered an AroioDAC and now I'm wondering which I²S Profile you chose for it:
HiFiBerry DAC Plus
HiFiBerry DAC Plus ADC
HiFiBerry DAC Plus ADC PR
HiFiBerry DAC Plus DSP
and for which reason. What are the differences between these profiles?
Any suggestions, anything I missed?
Thank you very much for your help!
