Yes - I understand you very wellActually, I meant that from the perfect power conditioner we firstly expect a complete purification, as if our wall socket would be ideal in all respects. And then, when all the flaws already fixed, we can add something new, that any wall socket can't give us. (Like balanced scheme, doubled frequency, Rick's magnetic conductivity and etc) This is my point of view.
Their is a "control" on Deep Core that allows for "normal and changed"... I agree with you - this is an important issue.
But if you fully complete the first, and add the second as user selectable feature - it's the best. I hope this is your way.
As to twin leads - we have made arrangements inside our topology for this. We can use output ground as drain - and our wiring works within this parameter...I'm sorry, but I didn't quite understand you. (As you can see I'm not very good in English) Please tell me more clear: can your devices work without grounding at all?
