Your combination:AC isolation/condition devices

And power cords. My experimentaion reveals that combining complementary (synergistic) products offers dramatic
refinement-particularly for CD enjoyment and preamps.
One example is the use of an Equitech 2Q balanced transformer with an MIT Z Stablilizer.
I think this is an area that merits our united attention and will effect significant enhancements, far surpassing the use of any one unit or brand. Discussion of the how & why technical factors, i.e. frequency ranges affected, method of the device, could be informative & very interesting if tech savvy members contribute. Hope so.

Equitech primarily addresses common mode AC line noise.
The MIT Stabilizer addresses differential noise.

Before you start looking that up, common mode refers from line or neutral to ground and "differential" or transverse or normal mode refers to noise between line and neutral. Common mode is the big culprit.

A shielded transformer is also a capacitive/reactive inductive load, which filter frequencies beyond 50/60 Hz. I've seen examples (not confirmed) of up to 8:1 spike reduction through transformers as well. What they don't do is regulation, except for motorized autoformers but usually too slowly for our intent. They also don't prevent ground loops because, by code, ground has to be continous.

Chose an industrial step-down transformer because
1) EI cores are not as close coupled as toroids
2) to get balanced AC out of either 120V or 240V
3) Picked up a used one for near pocket change
4) designed for demanding loads, not packaging
5) very high current requirement (5KVA/20A balanced)

Ngjockey,
"Politely"-- A step down transformer is not a "balanced transformer" and will not achieve the same results.
What do you mean by "very high current requirement"?
Please identify the brand & models you suggest and I will research & post results. Thanks
