Probably about 3000 or so between my wife and me (mostly mine). I can't vouch for the quality of all of them, though. Vinyl is limited to when I was a kid and my parents made me buy vinyl instead of cassette (smart folks!): Twisted Sister, Van Halen, Def Leppard, Iron Maiden...
We realized when we had to furnish rooms around our CD's that we needed to change things. We got binders that hold like 750+ CD's, put the jewel cases and booklets in the attic. Since I've ripped most of them, I barely touch CD's anymore. In fact, I can't wait till they go away. They drive the cost of music up (plastic, manufacture, distribution) and they limit contracts for bands, IMO (labels may be reluctant to invest in a major pressing of a disc).
Having all my music on my iPod just rules...I'm so glad to be done with CD's.
