Who here continues to regularly use a CD player?

Me too.

I have a CD player and use it often. A lot of the Super Deluxe Box Sets come with many extras on CD, DVD and Blu Ray. 

I also find a lot of like new CD's at yard sales for next to nothing...

I play CD's almost everyday and vinyl a few times a week.  Qobuz a few times a week as well.

Yes, I use my CD player, Cambridge Audio Azur 650C, regularly. Won't stream - services are more than I can afford. Have tried streaming; fun for the first three or four hours then I went back to my CD's and LP's. I like physical media too much and didn't hear anything streamed that sounded any better than my CD player.

I listen to CD’s on a regular basis, along with streaming and playing LP’s. I use a Kora Hermes II DAC, which makes the CD’s sound much warmer.
