Grounding issue

[Bigears]

Purchased a Topping DX3 3 pro plus and have noticed when powered up and touching it there’s a “ tingly” feeling in my finger tips. This tells me that there’s a grounding issue ? Plugged in a RCA cable and touched the other bare end an no “ tingles”.
Took it back to the where I brought it from. Set it up and “tingles”. It was suggested in a nice way that perhaps I should look at some different power set ups.
Anyone else had anything similar?

Common with ungrounded (Class II equipment) My Macbook does it when not connected to any other grounded gear. It results from very low capacitve coupling from the mains in the power supply. Nothing particular to worry about, it is very low energy. It will go away if you connect the device (via interconnect) to any other grounded (class I) equipment.

Most likely it’s your imagination, I get that tingling sensation when my fingers touch cold metal even when there’s no electricity around.

It can possibly be dangerous! You might want to get an inexpensive multimeter and measure the voltage between the case and power-line ground.

...When I was in high school my mother said she was getting a tingle from the waffle maker. I didn't feel anything and I was thinking it was her imagination. But I knew something about electricity and I was wearing sneakers so just to make sure I reached-over and touched the water faucet... BLAM! Big jolt through my chest! My first thought was, that was stupid!" I advised her to get rid of the thing, and I'm pretty sure we got a new one.

Open circuit, the voltage might be quite high. Touch it, though, and it will drop to near nothing. It is clearly not a dangerous fault: If it were there would be more than a tingle from touching it.

I once had a tv setup that consisted of TV, DVD player, AVR, Set top box, and Aerial Amp. All were connected together via interconnect and aerial leads. None were grounded (all class II), the combined leakage of all devices resulted in quite an unpleasant buzz when touching the connector of the aerial lead.
