I do not have DSC2 v2.5.2 or v2.6.2. 🙂
I can only rely on my memory. It sounds better.
With the BBB there are absolutely no problems with DSD512. The stability of Amanero on DSD512 is low.
The sound is highly dependent on the BBB firmware. So now I’m spending most of my time on optimizing Linux for BBB.
The firmware will work with RoonBrige and NAA HQPlayer.

Man if i could find a computer to encode multi-channel DSD, BBB + 2 or 3 DSC2 would be awesome.
I have been wondering if anyone has tried server platform that has multiple xeon cpu. The server would have to be outside the listening area, due to loud fan noise 🙂

You can use this information completely freely. If you plan to make changes to the project, I urge you to inform within this forum.
The maximum sound quality of this DAC is revealed when using the Signalyst HQPlayer.
v2.5.2 it is possible to install three types of transformers:
In the coming days, I will publish a set of documents for the new version of BBB/Amanero+isolator+recloker+DSC2

Hi Pavel,
May I ask you a favor.
I bought a set of transformers of the kind you suggested and was listed on Andrea's site.
The problem that I have is that I bought a second cheap pair from the same vendor and all came in the same box. I have no idea which ones are the more expensive Permalloy ones.
Could you point out on my attached picture if the ones
with the silver laminate core or the darker ones is the
right pair.
This would really help me.
Thank you in advance,
Klaus

Thanks Pavel
I want to encourage all those who have the differential version of this dac to
try the cheap TPA3116 boards from China as those chips have differential inputs.
Most vendors only use them single ended but my board from Yuanjing
has the second input from the differential pair tied to ground via a ceramic cap.
As you can see on my previous picture I simply removed the ceramic caps and attached wires to the vacant pads.
This combination just makes the most analog sound I have heard from digital.
My previous combination of Xmos/AK 4490 is not even close.
The details, spacial presentation, and the organic sound is fantastic.

Hello PPY,
Is it possible for You to zip and upload these same files here to Diy Audio (servers) instead of linking them only to G_drive so the rest of the readers of this very technically exciting thread can also access them. ?
- Some of us still trust a good firewall and intrusion preventer + key logging preventing softw. to not allow malicious cookies from well known sites to harming us as the visitors of theirs web - cloud services.
Thank You
