I'm still using my first surround equipment I bought eight years ago. My Yamaha BD-A1010 last had a firmware update in '14, yet plays 99% of my discs without issue (Steve Miller's Fly Like an Eagle is the only exception that comes to mind). True, I can't play Atmos, but I'm fine with that because I consider Atmos more of a movie format. My next receiver/player will be Atmos ready however, only because I feel if I'm investing in new gear it would be foolish not to get the latest technology available.How many decoders? And how often do you have to get a new one?
