I have bought several universal remotes in the past, but have always returned them because they could not command or learn several of my Marantz 7300's remote keys. It looks like the remote that comes with the 8200 receiver and up - the one that looks almost entirely touch screen - may be the one. Two questions: 1.) does it control all of Marantz's commands 2.) does it work well with the other non-Marantz components. Thanks for any help.
