The cat cable is the last thing to change. Why not try a Linear power supply? The power supply on the U1 and the U2 is the weakest link. Check out SBooster.
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!
