I ripped my CD's onto a NAS years ago, listened to them via LMS and a Logitech Duet and was perfectly happy.
Then a couple of years ago, my eldest son offered me a free Amazon Unlimited place on his subscription, (He has 3 children who all want to listed to different music at the same time), which I accepted.
This prompted me to buy a WiiM Mini to experience the higher than CD quality, and to listen to some new music. This quickly got upgraded to a WiiM Pro so I could continue to use LMS.
Now I mainly listen to my ripped CD's on LMS and occasionally new stuff via Amazon Unlimited.
I'm still perfectly happy.
