ok, lets leave the clerics marce, perhaps they have discovered the 'dark bit' ? one that makes it through an EAC ripping undiscovered and the sneaky little blighters then make it through several buffers and reclocking stages to ruin the audio by removing actual music bits, but only the audio, doesnt seem to ruin other data, must hate music? only seems to have an effect if you believe though...

just like you can have caps that are 'too good' for the opamps, because the 'analogue current' (not to be mistaken for digital current) sounds better through the higher impedance decoupling cap, which must have leads (actually this is where they switch to technical language and call it linearity)

but getting data from a to b has been worked on for decades now,
Just don't expect a .wav file sent sent to the other side side of the world via a Server such as Filemail to sound quite as clean as the original, with low level ambience unaffected.
Sending a .wav file as an UNCOMPRESSED Zip as Cookie Marenco does, helps to prevent low level degradation due to servers and numerous optical repeaters.The .flac container also appears to offer protection.
There has been extensive testing done in this regard with numerous recipients worldwide, including John Kenny and the designers of the well respected Windows software player "jPlay"
O.K. I am no longer a participant in this thread.

its only useul to a point, marce is right, the only and best way to deal with the PC noise problem is to disconnect it, add isolation and forget about tweaking it because you will never solve all the problems, we all know the wav will survive intact, just isolate then reclock locally at the dac.

so while its an interesting enough intellectual exercise, IMO its a waste of breath/resources

Do they work ?
Has someone tried a DIY on that, I guess the filtering techniques must be quite easy ?

BR
FYI, the item on that page is now $450.

These appear interesting though: https://coreaudiotechnology.com/prod...ies/dc-filters
