For PC playback, using Windows 10: FooBar, HQPlayer, Tidal, JRMC.
These are the ones that I use, FooBar seems to be a good troubleshooter type app, HQPlayer is well very specialized, Tidal is for discovery and JRiverMediaCenter is my main player. It is very versatile and I like it best for managing large collections of files.
I also use a C658 for streaming so I use BluOS, and I use a PONO portable player to drive my outside player system.
And in the garage there is a Raspberry Pi3 using Volumio to drive an old receiver for workshop tunes.
On my main system I like to use JRMC mostly, but I use HQPlayer for DSD and it perhaps can sound the best.
