You are saying current does not return to it's source? Show me where that was proven wrong? Current is current in this respect. Doesn't matter if it's AC/DC/RF/audio. That's the problem with many of these audiophile wire theories. They fail to recognize that audio is still in fact electrical energy when going through wire.
I am not talking about a new pole transformer either. That would accomplish nothing because the dirty household equipment would still be on the secondary. I am talking about dedicated isolation transformers for AV gear and only that gear.
Yes they do eliminate DC offset. But a good EI isolation transformer will also limit fast spikes and HF noise.
This is an old and well practiced technique in communications facilities. However today with UPS systems prevalent, the output transformer serves the same purpose.
Toroids of course are higher bandwidth so there use as power conditioner isolation transformers is questionable. And I realize they are still used by some audiophile vendors
But then many of the audiophile power conditioner manufactures lack an engineering background and don't understand that. They probably think a limited bandwidth power transformer will result in limited audio response!

Are you sure you aren't referring to a constant voltage transformer? In the traditional meaning of the word, an isolation transformer is a 1:1 transformer intended to isolate the secondary from earth. It does virtually nothing to isolate line voltage irregularities on its primary from the secondary.

A large EI isolation transformer will suppress fast rise time spikes. Basic frequency response problem used to our advantage. The same goes for HF noise on the line.
CV transformers (Sola's) typically produce bad AC waveform distortion. They make a model that is under 5% but still, these are not recommended for powering analog audio gear.
"The same goes for HF noise on the line."
I understand the frequency response issue. However, like most filters, the response of an iron-core transformer includes a recurring passband. Most ham operators can tell you how well line transformers pass RF. :)
