Fiber or Eithenet

Hard to believe. I thought it was a very large improvement using the Fiber over Ethernet cable. At least with my Lumin, which accept fiber direct without needing a conversion adapter. I did however purchase some very good Transceivers.

And I am going straight from my Lumin X1 to my amps. (No preamp).

I noticed no reliably discernable difference and compared them side-by-side more than a few times.  I am using fiber mainly because that is what my Sig Rendu SE accepts, and maybe a little because from a technology standpoint having zero chance of picking up EMI is still better than a small chance.  If I heard a difference, I would pick the one that sounded best to me so, carry on whichever way you hear it.
