Who here continues to regularly use a CD player?

CD only here.

An advantage of having been in this hobby for almost 60 years is having tried different formats and equipment.  When cd's came out I ditched vinyl and steadily moved up to sacd with Sony, then Marantz SA-10 which upsamples and converts to DSD using its own approach.  Streaming through it with an inexpensive unit and standard Spotify can sound pretty good but now I'm going to upgrade to a high end streamer/server and PCM dac.  I'll be able to compare dacs by using the sacd as a transport and streaming through both dacs.  Should be interesting.

I mainly stream music with a Metronome DSS to a Metronome Le Dac2. Sound is amazing. Recently my cd player stopped working as I mentioned in another thread. Replacing it with a transport is still the question for me, as I likely will need to spend a lot of money to get to the level of my streamer. But just like many of you, I have a huge collection of CDs (and LPs) collected over many years that I would like to listen to again.

My CDR is at the heart of my system. I rarely play any CDs though, I stream through it's DAC and also use passthrough monitoring for my TT because I can attenuate everything to the same level for my preamp tubes. No more changing volume for difference sources. 

In one of my listening setups I use a Denon 1700NE and the other a Marantz SACD30n.  Both of which I use about 30% of the time to play SACDs and red book cds since I have a few hundred of both.  Stream on Tidal and Qobuz the remainder of the time.   I have this thing about actual owning my favorite music.  Can I tell the difference in sound?  I really don’t believe I can
