No pops or clicks.
DAC performs perfectly with very engaging and textured sound.
I especially like the vocal and bass from it.

I am building a PC for HQ player to feed the DSC V2.5.2. Currently looking at motherboards. Do you guys use dual NIC (dual lan port) motherboards to connect your PC at the same time to to the NAA (beagle bone black or RPI's) and your network? Or do you just use single NIC and your network switch to connect to the NAA?

Any advice on important AM4 motherboards specifications or what to take into account?
How about an Asus RoG Strix X470-F Gaming mobo or MSI B450 Gaming Pro Carbon AC?

Asus RoG is a very good option for audio. The technology of Digi+ power supply converters is a real find for computer audio.

Perhaps I'lll look into replacing the inverters. Especially if it would work with the rest of the DACs I have.

The good news: I realized that BBB Botic driver has the option to invert the phase. So I connected my BBB->Hermes->Cronus -> BCK.DSDL/DSDR ->DSC2.6 and pin 10 to pin7 to provide DSDEN. Same noise as before.
Then I changed
Code:
/sys/module/snd_soc_botic/parameters/dai_format
contents from the default 16385 to 17409.

Boom! Perfect sound. There are of course pops from the DSD start as the mute is not operational, but I'll deal with this later - for now I'm quite happy.

Thank you Pavel for your help and continuing support!
Can you post some pictures of your Beaglebone, Hermes, Cronus and DSC2 setup? I plan to do the same thing and I want to make sure that I have everything hooked up correctly.

Thank You

Linux from scratch, not Debian. Sorry for inaccuracy.

This is not an image - any hints on how to install this? Just copy on an SD card?

Thanks!

Yes, it's very easy to go. Nothing special.

Configuring:
1. Network setting can be found in /naa/naa.conf
2. uEnv.txt contains optargs= line for configuring Botic driver (I use exactly this line). Just replace by needed. Full descriprion can be found at http://bbb.ieero.com/

How to start:
1. Format active partition of mSD to FAT32.
2. Copy all files from zip to this partition.
3. Edit network settings and uEnv.txt
4. Boot from mSD.

All info can be found in /README.txt

Here's the BOM I've used:

80-C1206X104J3JAUTO x2
595-ISO7320CQDRQ1 x1
872-920-0133-01 x1
712-CONUFL001-SMD x3
523-A-1PA-137-070B2 x3 (choose length to fit your setup)
Also you will need a 3.3v supply (clean if you will) from DSC side.
