Its a good idea at least to have one component in your system grounded.
That way if there is trouble, you have one route available.
More than likely local codes require grounding, and national electrical codes most certainly do apply.
If you have having noise[ground related]problems in your system, try this:
Grap a cheater plug, and try them one by one on your components, using this process of elimination, you can narrow or single out your ground related noise issues.
Be careful about powering down your preamplifier with your amplifiers running, most amplifiers don't react well to that.
It may well be that the problem is not system related, but building/home wiring related.
If its building related, you can always go the separate grounding rod route.....check with your electrician....
Some folks like to ground the preamplifier only.
Many amplifiers also should be grounded, due to the amount of power involved.
Also, I would check with Shunyata Research, they may not approve of negating the ground to the Hydra[I have one in a second system]. It could be a design issue, as some conditioners dump 'noise' into the ground[and returns/negative], as a matter of design.
I believe PS Audio now has a hum buster available....
I could really go on and on, but one thing for sure:
Its the safest bet to AT LEAST ground one component.
Hope this helps.
