Ripping CDs,…

Downloads are expensive.  If you already own the CDs, there are obviously savings to be had there.

What does the OP mean by “worth” ?

From a sound quality perspective, a high resolution download will usually sound better than a standard red book CD.  

@freediver +1 ... and there is the issue which version you get from downloads. "Remastered" does not equate with "better".

I use DBpoweramp and rip in full wav, the recordings are as good as Qobuz really they are. The only other option is to rip them in Ogg Vorbis at 500k .. this makes a good example. I never did like Flac it seemed to be a little like LDAC whiny ... LHDC is far better. Only thing is 1tb stores only 1200 albums but as the man said if you have the CD do it. Then you are ripe for a Bluesound Streamer etc. Make a couple of backup copies then move the CD to another or swap them.

I too have 400+  CDs and they are collecting dust and have been a Tidal member for approximately 10 years now. Guess part of it has to do with being lazy to get up and throw a CD in the player. I went through the MQA thing and never really came to a conclusion if it was pro or con. Guess I’ll never know. I try to go with the highest resolution of music whether it’s purchased or streamed. Just seems to make sense to me and agree with Remastered comment. This thread could go on and on and I welcome all comments and thanks for the previous replies. Long time audiophile here!
