Hi Miguel,
thanks for your interest.
The AroioDAC was powered from the RPI. I used one power rail from the dual power supply for the RPI.

PS: i have now own second AroioDAC. with it, i like to compare different power and isolator combinations


That's great, judydudi. I look forward to the conclusions of your AroioDAC power supply options comparison.

Do any of the DAC boards tested im Hamburg soundcheck use AKM DAC chips? If not, does anyone know of any RPi DACs that do use AKM?

Hi usery
Thank you for your interest in our soundchecks!
Yes, we had indeed a AKM I2S DAC in our soundchecks - The Terra-Berry 2 ( AK449 DAC and Re-clocking and up sampling by AKM AK4137)
see our previous posts.

There is a new product from terratechnos in volumio shop! The Terraberry 3
https://volumio.org/product/terratechno ... errydac-3/
I'm inclined to get one for the next soundcheck!

Thanks Jens for including the Terraberry-DAC3 in a future soundcheck. I'm interested in that board because I own a "mid-fi" integrated amp (Micromega M-100) with AK4490 chips in its DAC circuit. The sound quality from the M-100 ist natürlich excellent. I consider it "mid-fi" as an integrated amp + DAC since the M-100 costs slightly less than $5,000 USD ; )

Do you ever use a 'reference' hifi DAC in the Hamburg soundcheck as a baseline to evaluate the Raspberry Pi iS2 DACs? Any of the following or an equivalent hifi DAC would be a good baseline if available: RME ADI-2 DAC Pro, Technics NT-505, Benchmark DAC 3, Chord Hugo 2, NAIM DAC v1 etc.

@judydudi:

This is a great topic... I really enjoy, how you tell about these soundcheck events. I'm a bit envy, because I can't go there. :)

I just ordered AroioDAC, because it looks for me to have a great potential, since it was good without any power tweaks.
As the other guys told, I also looking forward to your improvements on it.

This is nice to hear. many thanks for the flowers. today is valentine's day. :)

update.
i was so busy. my plans are to do the AroioDAC checks end of next week.

Terraberry 3 is already ordered and shipped but hangs since one week in customs.

Great news from collybia: new DAC board there.
https://collybia.com/product/mamboberry ... khz-24bit/
Their love for the ES9023 DAC chip is further realized and perfected here.
They will sent me this promising board - many thanks to Emilios!

From IQaudio i have there new board 'codec':
http://iqaudio.co.uk/hats/100-pi-codec.html

Thanks for your interest...

Just wanted to thank you Judy for all these tests you do, I’m sure you have great fun doing it and meeting new people but for the vast majority of us here I’m sure I can safely speak for us all in offering our gratitude.
