My normally ever faithful Cambridge Audio 650BD Blu Ray has suddenly developed picture issues. As I recently purchased an LG OLED55B7V it's got me mulling whether to just upgrade to a 4K UHD Blu Ray player. I do have some SACD & DVD Audio discs, but not sure if I should allow these to dictate what player to choose. I'd certainly need one with multi region capabilities. Any suggestions on a player gratefully appreciated.
