Digital isolation between Ethernet hub and streamer

not biting.  enjoy midfi

Don't most good servers/streamers also provide some form of isolation?

@mitch2  - Galvanic isolation is required for Ethernet signals, but due to how capacitors may be used across the coils isolation could be improved on a bit.

Personally I'm more worried about surges from outside the home coming in and frying all my HT equipment which is cable connected to it so I like to put isolators which are rated to UL 60601 at the end of long cables, close to my HT switch to reduce those chances.  I don't know of any boutique/audio isolators however which have this rating. 

@erik_squires - I agree about surge protection.  Unfortunately, outside of a Belkin unit in my server/IT room, and my Isoclean Power A60 that filters all of my front end stuff in my system room, I don't really use it.

When I mentioned isolation for purposes of this discussion, I was talking about as provided by all the small boxes that are available to purchase.  Since running optical from my server room directly into my Sonore Sig Rendu SE Deluxe, none of the other stuff has done a thing for me.  I do use an optical break (2 converters and two LPSs) directly out of my router, and then after the server, I use Sonore's opticalModule to convert the Ethernet output into a fiber optic output that goes into my system room and into the Sig Rendu SE...

@mitch2 If you are already running optical there's very little you can do to improve upon that.

Unpacking your username, I see you love AUD. So do I, but I just can't get enough!

Do I understand correctly that you have a WiFi mesh router about 1 metre from your system?  And you claim it produces near zero RFI and EMI?

Surely the whole reason for having a mesh router is to blast the area with G-Hz WiFi signals?

When my partner moved her business into 'legacy' premises, wiring was going to be an issue so we (?) decided to go wireless for almost everything, including Voice over Internet Protocol (VoIP) phones.  In the end, we needed two mesh routers to boost the WiFi coverage.  These mesh routers get their packets via Ethernet cables.  They also get their power over these same Ethernet cables, injected as it happens though little wall warts which no doubt have switched mode power supplies.

Always suspicious the phones might not be working properly, she would often dial her business from her VoIP phones, not realising the VoIP system was smart enough not to route the call externally!  But then, a single unanswered call could cost her AUD 10k
