Best way to eliminate "common mode" noise from AC


line versus best way to eliminate "differential mode" noise from the AC line--not including AC regenerators with their attendant heat and ongoing power cost.

Thanks Gbart. I appreciate your taking time to be helpful but I mentioned in my initial query not including
power wasteful regenerators. I try to think green & buy the most effective,least expensive to maintain or operate, components. I think the Equitech 2Q transformer in a box & MIT combinations I use do an excellent job and are fairly economical to operate. So far I have never been able to justify investing even $3000 on a single conditioning/isolation component. But,I find isolation and conditioning extremely worthwhile and am seeking an ideal mix. I don't think a single component or brand will maximize results. AC noise is incredibly complex, and apparently growing moreso in microprocessor controlled robotics. My Spectral gear is 'very' revealing and cumulative rewards are proving satisfying & interesting. Hoping for more perhaps 'adding' a Shunyata or Sound Application product(s).
Need info/feedback. Thanks
Gbart is correct regarding PS audio, but if you are concerned why not go for balanced power?

Furman make some balanced power units. Remember the new PS audio regenerators are pretty efficient.
Roscoeiii,

Sorry I was meaning other balanced power units. Martin Glasband of Equitech known for his experitise with balanced power...

To add to my embarrassment I thought Furman made a balanced power unit that had a clever earth isolation system aside from the transformer LPF. (Not those 1 unit filters with pull out lights)

It was a few years ago, but I cannot find info on it anywhere. I was sure it was furman and that it was from their pro studio range and was a large 3 or 4 unit 19" rack?

Ah well. I would still go for the new PS audio regenerators even though the price is high.
