I have a high quality system capable of high resolution and have tried many different power strips including the $5-10. variety-- they generally sound terrible. If you must use a power strip for its many outlets, look for a good one, ie I now use a Monster HTS 1000 ($100.) for accessories, and short term have used it for components. It does not seem to color or degrade music quality/character.
That said, I use Synergistic Research Master Couplers (power cords) plugged into Hubbell Audio grade outlets that are the end of my dedicated AC system. All of this promotes a very low noise floor, quickness, deep tight bass, a pristine mid-range and smooth grain-free treble. You probably need a high quality system to take advantage of cleaned up AC system though. But it ALL contributes to final sound quality. Take it one step at a time, and listen, listen, listen. Good Luck, and Cheers. Craig
