But in recent years, a new trend has come on strong, and this involves the power cord, plugs, inlets and wall AC outlets. The point here is that the cleanliness of the electricity that runs through the components can deteriorate with standard cables, thus the power cable's job is to act like a line conditioner, cleaning up all the electronic trash. So I asked the electrician to use a high-quality power cord, and the amp came back with a yellow power cord. While it may be questionable whether it "improves" the sound, what power cables actually do is get rid of EMI/RFI pollution and remove other problems associated with standard power cables, allowing your system to perform better. So if you already have a good system and want to further improve its performance, consider not only high-quality interconnects and speaker cables, but also power cables.
