What was the best (most impactful) piece of new equipment to hit the market in 2023?

Sony’s 360 reality spatial sound mapping technology available for hifi use through their new ES line of receivers.

For me it wasn't a piece of equipment but rather software. I have been interested in the BACCH system for some time but I had no interest in inserting a MAC computer into my system. Their introduction of u-BACCH software for Windows corrected that. Running it through J. River l got exactly what I was looking for at a lower price to boot.

BACCH is from before 2023. Title of the thread is impactful stuff that became available in 2023.
