The thing is that since I listen to edm, lots of music I have is and never will be released in cd format. There are lots of singles and eps that are only available digitally. I've decided from now on that I'll buy everything I can on cd, but if unavailable on cd I'll buy a 320 Kbps mp3 copy off of beat port. I'm still going to rebuy every album I can though, I would very much like to amass a small collection of CDs.
Or you can use the money and upgrade your setup, which can actually bring improvement in sound quality.
