Jitter is not present in transfers since Ethernet doesn't work in real time (data in packets) and I doubt that electrical noise injected by the cable can affect sharp edges of DAC's internal clock enough to create audible jitter artifacts.
Electrical noise reduction is always good, but ask them about return policy (why to keep it if you cannot tell the difference?)
ENGLISH ELECTRIC EE-1 High-performance network noise isolator ? Yay or Nay?
Anybody personally road-test this brand new new streaming noise and jitter isolator offering from CHORD, just released ?
