.... subscribing to Tidal HiFi why do people still rip all their CDs to an NAS when just using Tidal playlists would be less hassle and give better sound quality?
Haha, yes, I've wondered about that myself!
... Although some folks report that ripping improves the sound of CDs.
I'm well into Internet streaming and the last thing I want to do is rip my 2,000 strong CD collection. I just stream everything I can from my Internet providers of choice. I really can't see the point of ripping them all, adding extra expense and complications to my audio system.
There are a few albums I like that aren't available streamed atm, and I keep a silver disc spinner (aka CD player) for those.
Btw, my recommendation is not to assume that Tidal is necessarily the best service to go for.
I've tried a half dozen or so, starting off with Tidal, as it happens.
They all sound a bit different from each other to me. Tidal is the most upfront. Deezer and Qobuz are a bit more laidback. Spotify the most relaxed and easy going.
Also investigate their music catalogues. They can differ significantly from each other. Depending on the music genres you listen to, one service may have a better catalogue than others.
My advice is to take each of them up with the standard 1 month free trial period and see how you get on with them.
Tidal has blotted its copybook for me in 2 ways. Firstly, I find the sound quality too upfront, it has an insistent unpleasant brightness to my ears. Secondly, some of the albums have become corrupted regarding the ordering of tracks. The dang things are all mixed up on quite a few classical albums I've come across. That's ruled Tidal out for me.
I've settled on Spotify, it has an unmatched music catalogue in my experience and for my music tastes. That's the most important thing for me, the audio system can be tweaked a bit to compensate for the more relaxed presentation if required. Spotify also has by far the best user interface imo.
All of the above is imo and ymmv of course! But it's definitely worth trying things out for yourself.
