CD or Streaming... am I missing out?

Whatever the sample and bit rate, analog is infinite.

No, analog isn't "infinite." It's bandwidth limited just as digital is.

Not bandwidth-analog has an infinite sample and bit rate.

Def CD.  My wife, occasionally, actually pays attention to what I’m playing. I was listening to my newly received Japanese recorded CD of Days of Future Passed when, from the bedroom around the corner, I heard “wow, that was so clear . . it sounded great.”  She did have a basis of comparison as every morning for about 3 weeks before it was DOFP on Spotify streamed through a Mac MB50 to a Mac MA252 to SF Olympica llls. And for me sitting in the sweet spot,  the richness and timbre of voices were definitely clearer and fuller on the CD.  But, Spotify has given me a universe of music for 10/month.  Best of both worlds. And my CD player is a Sony 300 disc changer. Makes me sad to think how much better the CD might sound with a “real” CD player.  

This is how I relate using streaming (either reading from a hard drive or from the internet): ‘Some people still think that using pen and paper is better than using computers.’
It was proven over a dozen years ago that reading music from a hard drive sounded better than reading it from a cd.
Also with hi-res source material: SACD, dsd, and MQA, these formats exceed vinyl.

Were that true, analog would have infinite resolution which, of course, it doesn't. You probably hold the mistaken notion that digital "chops" the sound into discontinuous bits, but that's not how digital works. You might want to watch this.
