Audioquest Vodka vs Wireworld Starlight 8 (Not Platinum) Ethernet

Yeah but it’s still using fiber to kill noise — same principle.

jjss49 posted the video in response to "And how is FMC better than ethernet cable?"  It did not deal with the question of how FMC is better than ethernet cable; it merely showed how to do it.

As for the popularity of the Sonore Optical Rendu, it is an Ethernet-to-USB convertor and not just an inserted optical link.

And, yes, the question would better have been answered by user comments.

This video is a "how to" but does not demonstrate or prove that inserting the FMC link does anything useful.  The speaker refers to "analog noise" but does not demonstrate or prove that such noise, which may exist, has any audible or measureable effect on the output of the DAC.

OK, OK.  I'll drop out now.  I was just looking for a different type of discussion.
