Manufacturers do not advise to change power cords. They already had thought about it while designing, listening, showing, and selling the product. Rest assure, they would not compromise their product over a stupid power cord. If they could make it sound better with a special power cord, they would.
Power cord replacement suggestions
If i were to delve into the fanatic behavior of replacing power cords, is there some concensus on where the most impact would be gained, whether on source, pre, or amp, or is it just different for every system and need to experiment. Thanks for any advice.
