As I've received a couple of PMs with this question: I bought my set from amazon uk. Four CDs are slightly scratched, nothing serious but they need to be taken out of the crappy paper containers asap
I'm only going to take out and store the discretely mixed DVDs in different and more accessible cases. The rest are remaining in the set cause I don't think I'll ever have much need to listen to the upmixed DVDs and all the CDs are on streaming services for easy access.
