Basic switch....should I upgrade?

@lalitk,

again: agreed. Given the substantial impact of the 10m clock on the Etherregen as well as the contribution of the Ocxo-switch I am not convinced that mere filtering suffices, though…

I guess the InnuOS Phoenix Ehrerregen is the most credible attempt by a manufacturer  so far. Disappointing, though that there seems to be no common clock between the two Phoenixes (Etherregen, USB), the server and the DAC in that model.

@antigrunge2 

Look out for upcoming Network Acoustics Rubicon switch.  A box like ENO inside a streamer / server would serve as a solid foundation to noise containment. Tweak geeks like us will always find a way to improve upon existing standards 😉

@sns What mods did you perform on your Cisco gear?

I wonder how much time the Engineers building modern recording studio's spend on the audio attributes of the Ethernet  network connecting their recording equipment? My guess would be about 3 ms.
