It is interesting, I'm certainly limited in my knowledge of such things, but half my gear has no ground pin, these are not low power devices either.
Subwoofers that can draw 1000 watts, an integrated that can draw 1200 watts, and one that can draw 800 or so.

Then there's Yggy and the Jot, 30 and 15 watts respectively, and they are both grounded. Everything I own is immune from hum or power line noise or I'd freak.
I do use DC offset filters on most everything.
I think the steady power from our nuclear power plant just 25 miles away doesn't hurt, I have very stable power usually.

Try lifting the ground pin. Most devices did not have 3 wire cords in the 70s and 80s, and many do not now. See what works for you. Roadies for musical groups go through this grounding barn dance at each gig.

I have lifted grounds to eliminate ground loops in the past, no need at my home now though.

Oh nooooo.
You know better than that.
The French better cooks than Italians?
Get real.

Wow, can this open a can of nuclear worms? What a fantastic thread!!

Just between you and me -- is that a good thing or not?

Ah, the mysteries of life.

A lot of professional gear has a ground lift switch which does that same thing. I’ve had to trouble shoot stereos by using an adapter (easily bought at Home Depot) to go from 3 pin to 2 pin. I have often tried that at home, and it has usually worked and never killed me. YMMV.
.

EDIT: Back when I started in on this hobby, the received wisdom was that you only had one piece of gear that was grounded. Everything else had a floating ground. That way the floating ground would stabilize to the one piece of gear that was grounded and eliminate ground loop hum.

As a result of that received wisdom, we figured out lots of ways to convert gear from three pins to two pin, including ripping the pin off of a power bar plug so you could plug in three pin gear but still have ground lift.
.

Steady Mates! Careful there young men! Ground lifts can kill !!! Particularly with 240V mains voltages. What grizzled roadies *sometimes* get-away with on their hot-wired Marshall guitar amps -- I personally wouldn't take such risks, to myself or to others.

Proper hum-free grounding can always be achieved safely, with a little bit of effort.

Aren't there some few million regulations for this?

Ignore regulations--they only exist to protect the lower 5% of the gene pool.

The gears I'm talking about is newer compliant stuff, and floating ground.

I don't know whether I interpret wrongly but I find most of @Pietro Cozzi Tinin posts to be satirical in nature. Why so serious guys!

Schiit, so no news from RMAF? I'm outa here for a bit.

Live music tonight, some redneck rock from Bad Company & Lynyrd Skynyrd.

lol wrong thread to come to if you're actually interested in Schiit audio or audio stuff I guess ?

It has its moments. Most of the Schiit product discussions end up in the threads for specific items. This one ends up being a bit of a free for all and covers most topics you can think of. If you do have Schiit questions ask away though I am sure someone can help!

You kinda took my post as a whole out of context. I have personally never owned a class D amp that wasn't a subwoofer amp before.
But until you hear these monitors on a desk I'd say your opinion of them is meaningless.

I would suppose Focal chose Class A/B for the beryllium tweeter, and the Class D for the woofer for a reason.

True but amp in active speaker or on a passive are two different worlds

If one takes himself to serious it becomes really easy to project this onto others.
If anyone was asking, I would say it explains a lot of things that go wrong in the world.

I said it anyway.
