I currently have a pair of 532-lr bookshelves and a 532-c center for front speakers from aperion. I wanted to upgrade to the 533-vac but they no longer have any 533-vac's in black. I even checked for a a and b stock with no luck. So my question is could I upgrade to the new 5C instead? How would that match with the 532-lr's? Thanks for any help.
