For example, better designs might include having isolated
transformers, balanced design technology, regeneration of

electrical grid injection noise.

You must be referring to US stuff. All UK equipment already has an
isolating transformer. It would be illegal to sell one without.


Some people have more money than sense. Better to
buy equipment where the maker has catered for possible
mains borne interference.

And, some people have bad credit (no plastic) which
prevents them from trying a free demo unit in their home
setup. Or they dont know any better. Which are you?

I know that you're advocating the spending of money that isn't needed.
Just buy decent equipment in the first place.


For a periodical review of these units check out
Stereophile issue Vol. 17 No. 12.

Love to know how you arrange for a 'dirty' mains supply
to be anything like typical.

Consider doing your own home work (empirical experience).

So I take it you just do 'subjective' testing then? Figures.
