Ahh! Yes. I recall when Marco excavated the garden around his house to accommodate his modest grounding scheme! ;)

Ethernet is inherently isolated. If you need greater surge protection say 5kv+ as in medical instruments then an isolator will provide it. The issues arise when you start using STP cable which will connect the ground planes of both end point devices together.
63 pages, and not many people are more aware of how these things work. :ner:
True, but some very useful and informative links have been discovered.
These 'grounding boxes' just didn't happen by accident. Their designers must have some idea of how and why they work - or was it a case of give enough designers enough bits of metal, gravel, broken glass, crystals, and someone will come up with a grounding box?
I worked in a laboratory where microwave absorbing materials were developed. They were, IMO, developed using 5% theory and 95% trial and error!
At the prices they sell for, there is enough room for trial and error. :eyebrows:
The chat about perception reminded me of an incident that took place when I was a student doing night watchman duties in a large metal plating factory. I'd got used to the place clunking away as the vats cooled over several nights but on this particular night I was walking along the central path through the warehouse when i got a very peculiar feeling to the extent that the hairs on the back of my neck stood on end. Wondering what was going on I suddenly saw a barn owl fly over my head! I'm pretty sure I can't have heard it approaching but I did sort of sense it coming. I don't actually think this is relevant to listening to music :) but I do believe we can sense stuff other than the obvious. I was at a meeting on Saturday where Alan plugged in his box of tricks. Although I pulled his leg a bit the first time he switched it in and out I had a "feeling" something had changed. With subsequent swaps I couldn't hear a difference - go figure :scratch:
Neal im not qualified remotely in electronics however;
Before i put this transformer in, a few weeks ago I did an experiment as i thought that my through the power network extender was was potentially an issue holding back my system. My network is router in the hall, network in power extender in the hall, network power extender in the hifi wall socket, netgear 5 port switch feeding apple Tv and TDAI3400.
My hifi network cables are chord c stream which is shielded per conducter and a sheat shield, but the router end is UTP. I took a 15m UTP cat 6 cable and ran it directly from my router to the Network switch. Played 4 tracks i knew well, then took it out and played them again with the in power network extender. Sat with my wife i thought i heard a very small improvement to the high end with cymbals etc. My wife said i was imagining it and it certainly wasnt enough to motivate me to put in a direct hard line.
Now with the transformer in between the hifi in power extender and the network switch seriously big improvements. I still have netgear switch on an smps but i keep it on a seperate power strip to the rest of the hifi with the cd player that i dont really use. The only other thing i changed was re organising the cables in the netgear so i used 1 in 3 apple tv and 5 tdai. Previously i was using 123.
