Opus88,
I suggest you check out this fantastic thread Finding Pure Water for Record Cleaning for everything you could possibly want to know on this deceptively complex topic.
And Guido, as a great admirer of your witty and informative posts, I'm afraid your aqueous expertise is in need of some serious rehydration! Distilled water and deionized water are similar, but definitely NOT the same thing.
Perhaps your confusion stems from an error in nomenclature, for when you refer to "Hydrogen dioxide," surely you must mean "Dihydrogen monoxide," the dangers of which are all too well known!
Also, your idea of filtering water through a bed of Tourmaline Granules is completely ridiculous: every serious Audiophile knows a jar of Magic Pebbles located anywhere in your ZIP code will work far better!
