@invalid - true with Sony, but engineers were easily able to show jitter issue with DACs. Nothing fancy. Audio CDs were never designed to be bit perfect delivery of data. But networks are.
As is USB protocol. We don’t connect hard drives, smartphones or cameras to PCs over SPDIF or Toslink for a reason. But we don’t lose phone backups, pictures or signed house deeds when sending data over USB or networks. Financial industry operates over same protocols sending money. Military send missile launch orders.
"Ethernet cleaners" can never explain what is that they do.
And for some reason cloud datacenters that stores all those Tidal files never use $$$ USB or Ethernet cables. Google network engineers would have a good laugh if offered 'cleaned Ethernet' or 'upgraded network cables'.
