isolation transformer vs line conditioner

Well, to the best of my limited knowledge, an iso transformer is only that. There are no other parts involved. Line conditioners, on the other hand, use capacitors, chokes, and perhaps resistors to try to clean up the AC, although some designs are very simple.

Iso trannies limit available power if they are not big enough. Line conditioners are only as good as their circuit design. If I understand correctly, a single good-quality capacitor between hot and neutral can short out a lot of hash. More complex circuits may work better, or may not.

That's all I know, and it ain't much.

I use a dedicated AC line, an Enacom line conditioner (a very simple design), and two iso trannies on my digital source and preamp. Each measure made a difference, and the sum is, well, it would be getting there if I weren't having a forced layoff due to fire.

Aball, where can I see those output waveforms myself? Or if I can't (without setting up a 'scope on my line at home), then could you describe such a waveform?

I ask because the evidence of my ears suggests that my iso trannies are doing something right.

TIA !

Sean, I know you are characteristically forgiving of ignorance...

... most power supplies are lacking, hence the great variance in power cord effectiveness from component to component.

When a component gains a lot from a power cord upgrade, does that indicate it has a poor internal power supply, or a good one? I would have thought the former, but am I right?
