Are there more ways you find it 'better' than mentioned in your post. I love that word as it means so much to us, yet is almost guaranteed to be a preference that is completely & utterly unique to you alone.
I'm a recent convert to NAS & rapidly found myself wanting a cd player. Streaming music on a hifi somehow allows me to drift off & not experience what's happening in the present. I'm a huge fan of the tactile & physical ritual of loading & playing albums..
Just now I realised that I'd say physical media is 'better' as it keeps me present during music listening. Quite literally, knowing it will stop or need to be flipped over forces me to be there & feel how music pervades my whole nervous system. When streaming, I do feel less connected to the music, esp if it starts playing recommended songs after an alum has finished.
