Digital isolation between Ethernet hub and streamer

@audphile1

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

Thanks for clearing that up for me!  You did originally post 'near zero' but now it is a 'good amount'.

My partner really believes there are four types of matter: electrons, protons, neutrons and morons.

By and large, we 'audiophiles' are a pretty gullible lot!  For fifty years we have been fed that digital sucks. Most audiophiles stick with two channels, 25 years after multi-channel came out. Then we discover that for two decades almost all records have been mastered digitally!  And those same record-loving folk now laud streaming, which is digital, even if done badly.

I wish contributors would back up claims of clear audible differences with a bit more evidence.  How hard is it to get somebody to switch a power cord while recording what they have switched and whether you think the sound is better, worse or the same?

I tried measuring the effect of lifting my dustcover and surprised myself with the lack of attenuation of pink noise, compared with white noise.  There could be a sensible debate there
