I can't understand much of the conversations, but from images (amplitude vs frequency) related to a test with an AK4493 DAC (if I understand), it seems that PPY Re-clocker is very clean, like McFIFO and slighty better than Amanero!! Good result!

Yes, the result is good. I myself did not expect this.
Not high cost and compact size - a very good option.

Hi Pavel, do you hear differencies between the old DSC 2.5.2 plus the new Re-clocker and the new DSC with the re-clocker on board ?

... and does the stand alone isolator-reclocker use the same hardware of the circuit "embedded" in the last DSC2 ?

Last question: What's about in using the cheaper and newer Beagle Bone Green?

Thanks

I can not compare the sound. v2.5.2 and v2.6.2 not available.

Of course there are some differences.

BeagleBone Black was the first and last. All other 4 only bought BeagleBone Green. I like Green more.

Default My DSC2 build

After some intense soldering (luckily mostly with a modified toaster oven for reflow and solder stenciling), my DSC2 is up and running. I am using LL1684s, Vishay PAT tantalum nitride resistors, and (presumably NXP) 74AHCT595Ds from Taobao.

I am using a BeagleBone Green with ppy's latest botic image without any hiccups. I'm converting to DSD512 and streaming from Roon.

Power supplies are 5v for the BeagleBone and ~7v for the DSC2 provided by xrk971's, CLC / CapMX / Regulator board: GB for Simple Cap-Mx Regulated Low-Noise PSU. I'm using a boring LDO for the BeagleBone and a TPS7A4701 for the DAC.

ppy, thank you so much for providing this awesome and challenging project to the DIY community! I have really enjoyed my time listening to the DSC2 and it will likely replace my long standing Soekris DAM1021 and RPI combo on my main system.

Do you think you'll be making the buildroot sources / configuration for the botic distro you created available? I am going to be adding a SPI OLED display to my build, likely driven with a simple python program to display information from Roon, etc. I would love to use your distribution as the base for those customizations without having to reimplement the botic patches and configurations on my own.

Yes, I am ready to open buildroot sources for this firmware.
I am very pleased if the project will develop further.
I need a day or two to prepare and clean up garbage buildroot sources.
If you could check and fix the web interface in PHP? I would be grateful to you. I am not a programmer, and this was my first experience in creating PHP scripts.

P.S. gtose, good and neat work.

gtose,
I see you also use a kitchen plastic cutting board for DIY. Very comfortable!

Awesome job gtose, very neatly done !! How come you chose the lundahls for the output stage ?.

I see you are using a toaster as a "reflow machine". Some time ago I bought one toaster too for this very same purpose, but never had the time to finish the project. Yours looks great, how happy are you with the results ?. According with your pics it seems the controler is the Controleo3 (can be bought here just in case Buy Controleo3 ).

Out of curiosity, may I ask where you had the stencils (and pcb) done ?

Again, congratulations for your project.

cheers
.Pepe.
