Last news from my DIY Soekris 1021 project.
Change of main amplifier to Pathos Logos Mk2 I have changed outputs from DAC to balanced.
I'm usually not using connectors if I have possibility to connect wires directly.
It was very strange when I have feel some power loss from my linear power supply.
I have used 3300mF per +/- channels with LM317 stab and filtering scheme. In RSA outputs wasn't any issue here, but now… 🙂
So to be concrete - I changed Power supply to use 8800mF per channel instead and put small shield from brass to isolate transformer from DAC.
It works with balanced outputs - the sound more clear and detailed bass has more structures.

Hi,
the Soekris webpage appears to be down for me : https://www.isitdownrightnow.com/soekris.dk.html
Did anyone recently had answer from Soren?
Or maybe have a rev7 board for sell of dam1021?

A website can be down for many reasons but if he is closing shop I would think it would be prudent to announce it here.

I stopped following this super huge and descriptive thread on DAM1021 about 11 years ago and since then I am listening through a 1021 rev2 driven by amanero and raspberry i4 with Volumio. My problem is that my current speakers are very very efficient, thus it is now annoying to listen to a huge click every time I change a song. I was wondering if this simple problem of muting is already addressed during these 14 years or everybody still listens to this annoying noise. If there is a simple solution I would be happy to build! P.s I have the original soekris software and I have not upgrade it since. I recently installed some 1:1 trades at the output just in case the there was a dc during switching but no luck with these too.
Thank you!
Thank you!

Sorry, I did know that it is out of the scope the fact that this dac design produces annoying switching noise.
No this is only your suspicious.
The fact is here 553 pages and huge amount of users haven't observing switching noise not in different SW nor with Volumio. 🙂
