I have a computer audio setup and still buy primarily used cd's, as high res downloads offer very marginal if any improvement to my ears. the benefit is being able to browse and cue up songs on your i-device without having to get up from your listening chair, create your own playlists, etc. I do still use physical discs for playing back multi-channel SACD's.
Computer vs CD/SACD discs
I am simplifying my system and getting out of vinyl. Actually sold all the vinyl and analog gear already. I was planning on going to computer audio and have been playing with it but really don't see the benefit over just slipping a disc into the tray. I also am getting a bit frustrated by all of the options of downloads, cables, inputs and opinions all over the place. I would welcome opinions thoughts on computer audio vs the old fashioned, putting a disc on the tray and pushing play. ( Streaming, I use spotify, exempted as this is a nice way to demo new music).
