Ok with me. So if i used one dedicated circuit and lifted all the grounds but grounded the Pre to a copper rod would that be an issue with code ?

Yes. Bye the bye, the mains safety ground on your CAT (or any CAT including mine) isn't hooked up to anything. While Ken provides a 3 prong IEC inlet, the safety ground isn't attached to anything. Same thing goes for current Ayre components.
The issue isn't 'Code', the issue is that your insurance company isn't going to pay a claim if they can plausibly argue (even if it really isn't the causal factor) that fire, death by electrocution, etc... was caused by your 'improvements'.
Your are free (within Code) to add a ground rod at your service entrance, but it must be bonded within a certain maximum resistance to your present service ground.
