I've been using my RC2000MkII for ~5 years now with a number of different receivers, and it does controll all basic functions. All I have to do with it when I get a new piece of gear or change (Marantz) receivers is plug in the codes for any new functions. I didn't like the touchscreen (3200 aka Pronto) that came with my 8300, so I use it in my bedroom because I only need CD, volume and on/off. But it is nice that I can go from one room to the other with either remote and still use them for the receiver/amp.
