When femtosecond timing differences are audible, increased clock phase noise from crap switches, SMPS, and high-impedance leakage currents all have an audible impact on digital bitstreams. Swenson is working on a white paper describing this in-depth, & he is working on bespoke metrology to provide measurements that demonstrate this as well. Once soon as that white paper is available, I will reference it here.

The phase clock you are referencing only applies to Synchronous Ethernet. Synchronous Ethernet is not used on computer networks; its only used on cellular networks, VoIP phones, IPTV. Ethernet computer networks do not carry any clock synchronization information whatsoever.
If you have a DAC that requires an external clock generator via the ethernet cable, then you are injecting it yourself. No home router, etc., will support doing this..
