After doing some reading, it appears the BDA-3 will be controllable via ethernet? That'd be a nice change. My SP3 and BDP-2 are ethernet controllable, as are my Tivo and Oppo. If the BDA-3 is also, I could move to an entirely ethernet controllable system and get rid of the IR sensors!
I wonder why Bryston doesn't usually put the 3.5mm IR jacks on the back of most units. The SP3 has one, but the BDA-2 and BDP-2 don't.
