That makes me a bit sad

Looks almost identical to the Kato cable

I think they mean USB for the DAC

What closed backs have you tried?

On my AirPods, I love them. Especially since the Pro 2s added volume support

1. sometimes people need more mobile setups.

2. not everyone is rolling dough

Something can be mainstream without the vast majority of people using said thing.

That was also almost 30 years ago. Mainstream VR has been a thing for 5+ years

Depends. One of the common sorts of detectors is called a scintillation detector, basically it’s a big hunk of special plastic/glass with a camera attached to it. When particles decay inside the material, they release photons of specific energies. These photons are then detected by the “camera” and the intensities of the photons can be used to figure out what particles decayed and what the energy/mass of the particle was.

Another kind of detector relies on a semi conductive tube with a thin wire passing through it and an inert gas filling the space (proportional tube particle detector). The exterior tube is grounded relative to the wire, which is held at a high voltage to induce a steep electric gradient inside the tube. Decays and electrically charged particles passing through the tube will create a pulse along the wire, which can be measured.

This is well known. Nothing new here.
