I've found that (in general) components that have lower quality power supplies can show more discernible improvements than those with extremely high quality power supplies.
Today's electronics are capable of pretty good resolution, but the more "cost effective" power supply used in the more affordable components tends to reduce their capabilities. A good power cable will augment a less capable power supply and benefit the components overall performance.
e.g. my Bifrost DAC, with a small transformer, achieved considerable improvement, whereas my NAIM amp, which has a large transformer, showed little improvement when using the same "quality" power cable
