Etalon ethernet isolator.

Haha no problem Celts88, we all have our own truth(s) and beliefs. Baconbrain asked a similar question (whether using a GISO isolator which is similar in function to the Etalon would negate the need for an expensive/HQ ethernet cable) in my system topic. My view on the matter here: http://devialetchat.com/showthread.php?t...8#pid50138

But I'll also copy-paste it here: (just my $0.02 in a hobby where logic and general/common knowledge of computer science don't always seem to apply, at least not when there's a sensitive D to A conversion involved)

Could be, though I employ optical isolation and the ethernet cable still matters significantly. Of course the fiber media converter is an active device so produces its own noise. The AQ cable is connected between this converter and the microRendu BTW. I'd like to think only this last cable after the optical bridge matters and anything before it doesn't but I haven't tried any before so can't be certain.

Often many of these isolator/re-clocking/regenerating devices, even while working in tandem, all help in some way. There's really no silver bullet I know of. So there's only one way to find out when and how enough is enough and that is to try it in one's own system. 

At least in theory the complete isolation due to the optical conversions should be superior but even that to some people who tried this Etalon isn't true. It could be this is because of the FMC (fiber to copper ethernet converters) creating its own noise. Even the PSU powering the FMC matters.
