Amazing that you use all 20 channels of your processor. Looked at your setup and see you have a lumin X-1, which I also have. See you have a Vinnie Rossi integrated, I looked at the Brama preamp they offer but went with something else due to delays in producing it.
Also see you use a grounding box and wondered how you like it and how you believe it has impacted your system and rationale for doing what it does.
