CD or Streaming... am I missing out?

Streaming all the way, the sq is of course dependent of your source...I went throughout the upgrade path from lumin D1, T1, and finally X1. There is no turning back for me, especially with tidal choices vs my cd library which I now rarely use.

@mofojo local files still do sound better to me than Qobuz, but I'm happy to listen via Qobuz for new music and other music that I don't have locally.

You are missing out if not streaming.  Sound quality is not an issue.

Although I do stream with Qobuz, and the sound is very good,
 on my system, streaming sonically comes in last place to (in order):
 LP’s, SACDs and red book CDs.
The difference in SQ amazes me every time I play a record.
Of course streaming is much easier, and it has a limitless variety of selections.

In my experiences from a long upgrade path with cd players and streaming, hi-res streaming beats the cd for sq.
All the other reasons to go to streaming suggest to me that the cd is on the way out and unlike vinyl, will disappear in time as a choice. Streaming looks both forward into new music discovery and back into the history of music. Cd's are all about looking backward into music you already discovered.
