Well, the Class-D EMI filter was a huge disappointment! I soldered the little surface mount components directly to the speaker pins, that's better than they could be on a circuit board. It didn't change anything that I can see with the remote control, it still starts the first sound great, but if that sound is running, you aren't going to trigger any others from more than about 5 feet away.
If this is going to work, I'm going to have to find a better RF remote control package I suspect.
