I dunno…
It always kinda struck me as fairly straight forward.
There simply couldn't be ANY metal wire connecting the 2 'devices' together in any way in order to claim true galvanic isolation.
I mean that is what "galvanic" is all about right?
The minute voltage differential between to different metals when they touch.
And if they don't touch then true Galvanic Isolation has been attained…
At least that's what works for me.
And when I added a FMC (Fibre Media Converter) between my dac and my computer (along with an AOIP box in the middle) there was a noticeable change and in the ways I define as 'Better' at that.
And all it does is electrically isolate my dac (with an RN3 in the middle) from my Mac, via an optical link.
Oh, and it cost ≈$135 for this experiment.
Was it a Huge change?
No, but it is a ≈15-20% improvement (just above the ToP (Threshold of Perceptability)), and when added to all the other similar (10-25%) improvements, well, it all adds up after a while.
