Good question.
I don't really regret or miss any of my former owned B&O as it was always an upgrade of some sort.
From Beovision 8800 to L2800 and then LX5500.
From non B&O to 2000 and now 6000+ 8000 both '80s.
Now the number one question is if I could only use 1 system what would it be?
Getting other B&O in most likely means something has to go and I'm going to miss it or I had my experience with it so it's ok inside.
I buy for using it so if something is spare or not used I have no trouble in getting rid off but it has to be working right.
