I’ve bought a Hiby R3 Pro II a while back and it’s amazing. The build quality is top notch, the battery lasts for 20+ hours and it has basically everything one could need; USB-C, Bluetooth with Apt-X and LDAC, a good screen and a balanced output with plenty of power.
Even rudimentary support for Tidal and Qobuz. The only downside is that there’s no storage built-in, but you can use microSD cards up to 2TB.

GNU/Linux is an OS Kernel on which many many different operating systems (called distributions) are built.
It’s quite a bit easier to think of Linux as a family of operating systems, though. Are you thinking of getting into using Linux? I would recommend checking out Linux Mint as a beginner friendly distro with a familiar interface.
