Noise. That damned demon you may not even know about...

...I think the Luxy stuff is still double-insulated chassis, floating ground, Class II, whatever they're calling it. Esoteric too IIRC, although the Luxy is what I had. None of that Shunyata ground stuff was recommended for that gear.

...Japanese gear typically has a "floating" ground, not tied to safety ground. Not all, but not uncommon, for example.

Floating ground is class II and my TAD system is class II.

Is Proper class II design better than class I design? I do not know the right answer but I think so.

we have no need to have earth wire and the earth wire in class I equipments are just for safety.

check here good article from benchmark audio

It seems the best audio installation is :



1- all transport/dac/pre/power are class II (no earth wire, 2 pin ac input)
2- all xlr interconnects are like the picture (capacitor parallel to resistor at the end of xlr connector)
3- the chassis of all transport/dac/pre/power are connected (star ground configuration) together with awg 3 ground cable

In this configuration there is no ground loop

Esoteric is class II?
