Romy, even though code-conscious electricians install your special ground rod for you, they will still in all likelihood want to tie the neutral wires from your dedicated 30A lines back to the ground bus in the breaker box where they get their 30A feeds. As I have mentioned before, if this is a sub-panel, you would be well served to keep neutral and ground wires seperate all the way to the service box/main ground bus.
As you know, having separate earthing points for neutral and ground precludes the classic star grounding scheme, and ground loading can become quite compex as the system stacks up. I wonder if your new hi-fi ground will have less resistance than your house main ground, and without knowing how your gear drains internally, I wonder how this will play out in terms of optimal routing. What a luxury it would be to measure, pre-map and route all grounds against a pre-stacked system before so much as installing the system! This is usually how serious recording studios do it, along with all-balanced lines; but I have only known of one home system that was pre-engineered in this way.
