Suggest using Susumu thin films, but I do not know if Pavel (PPY) listen tested to a bunch of resistors. Even Susumu thin film in .1% is not too expensive, and the extra precision might be of value (this has been disputed here a bit).
Hello,
the resistors in the BOM are not available at mouser. Can you recommend an alternative?
Kind Regards
Stephan

This Part...
This part is not fast enough for USB audio. Only the newish Silanna chip can do it. Anyway, you want to isolate the I2S lines, isolating the USB is not of that much value. PPY's newest design has built in isolation/re-clocking of the I2S lines, or DSD lines of you prefer.
I having ADUM4160 USB Isolator - It's full speed by 12Mbps. How about the speed need for Amanero?

I tried Susumu RG series - I did not like it.
The latest version of the DSC specifically made resistors on the connectors. That it would be possible to quickly compare different types of resistors. Still tantalum resistors are the champions of the beauty of sound.
Unfortunately, BOM resistors are hard to find. I do not know any other cheap tantalum resistors.
You can try VISHAY tantalum resistors of the PNM PAT PATT and PTN series. But I did not test these resistors.

Would this be a correct supplement?

PPY,
this one is the only one I found that is available. Is this Tantalum?

Good and not expensive option.

How about Vishay NOMC?

Why not to push it to extreme and use most famous nude z-foil

TotalDac uses their through hole version in his R2R dacs.

This is mistake. Pin 1 U21A should be "0" In gerbers this will be fixed.Why dont use DSD-OE and Mute Pin to control the Enable Pin of Isolator Chip (as ISO7640) for remove the digital relay on the output signal line of DSD. Response speed of digital relay can make an bad affect the quality of analog output.

I'm sorry. I mean are Pin 11 (Mute) - It's 1-high when change sample rate. In your schematic, Pin 11 used to select the NDK Reclock (Amanero at Slave mode). So, If you only use the DSD-OE pin, when next/pause can do the pop?

Yes, NOMC resistors had good results.How about Vishay NOMC?
New DSC2 version - http://puredsd.ru
Made some cosmetic changes in gerbers and finished setting the firmware for this version of the DSC2.
