Just curious if I am asking for trouble if I use the ground scheme in the attached image. The picture shows only 2 LM3875's connected, but I plan on having 6 connected in this way, 3 at the top, and three more at the bottom (mirror image). They will all share the same supply rails and ground bus. Is this scheme likely to cause any ground issues?
PS: The boards are an obvious adaptation of the Brian GT ones.
