Mapleshade Records sells a power strip/conditioner which does not degrade sound quality, quite the opposite in my experience. There is also an option to protect from surge which is stated to barely reduce performance.
Into the adjacent AC outlet and any unused outlet in the listening room one can insert micro-priced parallel blockers of EMI/RFI called Flying Saucer (strangely named) from Machina Dynamica, to gain even better sound reproduction.
Finally, another very great added sonic improvement results from wrapping Animal Magnetism (another strangely named item from Machina Dynamica) covers around each power cord. As I would say at this point, "the silence is deafening." The quiet black background then allows a truly beautiful clarity, letting the best qualities of your gear shine through.
These ideas are quite low priced, without any impressive outward physical appearance to suggest the great benefits which are heard.
