Is anyone still using a CD Player

Remember, using your CD player is effectively, using another DAC.  If you like the way your streamer sounds compared to the 505's DAC, then do you.  But maybe it's a good time to look into upgrades or refreshments for the 505.  It was released 20 years ago.

When I get cds  3 for 2 dollars ...yes I'm buying them like crazy.

I'd like classify sound into two areas.

1. sound for information

2. sound for musical listening

When I work in fitness, I see many people using wireless headphone. The headphone produces musical sound from their smartphones. So many electric/electronic steps between the two. I can say the musical sound is no longer of musical feel. Just sound.

When you think just sound is ok for simlicity/brevity that's fine. But not fine to me.

Playing CDs in a CD player is the best musical quality as long as confining to my environment. No big $ needed, economical for the high quality musical sound.

Of course!  It's a great music medium!  That's all I dare say for fear of being banned again.,

YES to CD's. Also to vinyl, cassettes, and streaming. Yes to a CD-transpor to an NAD amp w/ a built-in DAC and also my desktop stereo w/ CD as a transport to an external DAC, as well as a Mojo 2 for headphones. Open back and Closed back dynamic and planar cans as well as Focal Bathys for out and about via bluetooth.

I collected records starting in the 60's. Then also cassettes when they rolled out. And later CD's for a number of years. From a Sony Walkman to iPod and then iPhone listening as well, which finally developed into streaming. Tidal/Roon, w/ my CD's mostly all ripped to a drive. I usually also have the Tidal version of my rips in the catalog as well.

Now when I purchase music it's mostly vinyl.

I love having all the options and doing what works best at any moment. My CD's, of course have booklets w/ lyrics and pics, and I like that.

Lately I've been bluetoothing to my new JBL Flip 7 from my phone when I'm in the kitchen or hanging at the dining room table. I play music a LOT of the time, and all the formats are cool by me. Even cassettes, which obviously are not audiophile-grade listening, but the sound of them takes me back and I really dig them. Also they came w/ little foldout artwork that I like.

Whatever works, but I would suggest that the method of music delivery is not as vitally important as most audiophiles make it out to be. Sometimes I want great sound. Other times there's stuff going on, window a/c on, people cutting the grass outside, kids playing outdoors, blah blah, and I just want to hear some tunes.
