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.
