Argh, now you got me interested, so shot!
What could have happened to make you to get rid of all your CD's?

Incidentally, there was something that happened to a neighbour long time ago; He had a vast collection of jazz/blues/rock LP's, and when the CD's came out in force and LP records were considered old fashioned he sold off all his records on fleamarkets...

He only later realized that the mastering of the LP's is far superior to the compressed production chain of CD's, and furthermore many of the records he sold off are never going to be released on CD again...

So for the last 30 years he has been slowly trying to build up his old collection by buying LP's from all around at way more expensive prices than what he once got for his collection...
