In my mind, it doesn't make sense to connect devices to the CGS that are not connected to the Triton via a power cable. Especially if those components are on their own, seperate circuit. Of course, I could be wrong.
I have ordered some spades and will build some grounding cables to try with my source and pre, which are the only devices attached to the Triton. Since my amps are each on a seperate circuit, and not attached to the Triton, I quess I will try it, and be surprised if it does make things better.
