As others have mentioned, get a switch with its own clock, an LPS for your U2, experiment with the fiber optic route or an ENO filter, better cables, and of course a better DAC eventually. IME every step in the digital chain counts, and ignore the "its just 0 and 1s" trolls.
Where should I go from here with my digital front end?
Good morning
My digital front end consists of a recently purchased Lumin U2 Mini hard wired with Supra ethernet cable from an Eero mesh unit. Modem and Eero router located on 2nd floor. My listening room is in the basement.
My listening is 100% streaming from Tidal and Quboz with a budget of under $1k
should I:
1) upgrade the supra cable
2) add an Etherregen or Eno filter
3) add an audiophile switch such as the English Electric
4) other
Thanks!
