Sorry to throw a spanner in the works here, but if you rip your CDs, my understanding is you have to keep the cds as proof of ownership and your right to rip them in the first place. If you don't, you could be prosecuted, unlikely though that might be.
Secondly, even if you back up the rip, you might want to re rip your collection to a higher quality storage medium , as I did.
My concern is a more depressing one, what happens when I fall off my perch, I'm 70+ now. I have about 2500 LPs and the same number of CDs. I don't want to burden my kids with getting rid of them. Amongst that lot are some valuable albums, MFSL, Proprius, Opus, FIM and so on. Dealers I know, will rarely take whole collections and will give a derisory sum if they have too. So, any thoughts?
The plan at the moment, is given some warning, to go through the whole collection, pulling out what I think is valuable and suggesting to the kids to E=bay them, or do it myself. For the rest, I would advise them to get dealers in and let them chose what they want, perhaps the rest can go to charity shops.
