Default PureDSD DSC2 stuffing guide

Stephanlj, thanks for your impressions on the LL1684s. I ordered and received a pair from K&K Audio and am looking forward to trying them out. Did you add any additional loading / snubbing to them? I saw some recommendations on this in Signalyst DSC1, though I'm not sure if the latest PureDSD DSC2 has footprints for them.

I'm not sure who on this thread is going to be building the PureDSD DSC2, but I have put together a guide for component placement to use when I start my build. The silkscreen is ambiguous for some of the 0603 / 0805 parts and I have attempted to document the correct places for these components. I did this by hand from the schematic and Gerbers, so be forewarned that there may currently be errors. I have attached the guide and would appreciate a second pair of eyes - and wouldn't suggest using it without it getting a second review.

Greg

Greg,
DSC2 has connections for LL1684, Pavel wrote that he did not install a snubber and that people told him that it sounds better without.

Progress on my DSC2 project has slowed down as I have some trouble-shooting to do. If I try to send music to it from HQP the networkaudiod process on the BBB stops. I'll disconnect the BBB from the Hermes/Cronus and try to get it working on its own with its internal clock and then progress from there.

Where to buy the SMD sockets for the resistors array?

Can I use 22,XXX & 25,XXX clocks in place of 45,XXX & 49,XXX?

Yes.
For BBB you must change the parameters in /boot/uEnv.txt
snd_soc_botic.clk_44k1=22579200 snd_soc_botic.clk_48k=24576000

The link shows DC conectors not SMD sockets for resistors array.

I use Amanero & I know how to convert Amanero to slave, thank you.

I don't see:

U1, U2, U3, U4, U5, U6, U7?

Amanero needs his own PSU or is feed from DSC 2.6.2?
