I recently found great improvements in my system with the low end Silnote Posideon and Shunyata Venom 3 PC. Both are around $100 and offer a 30-day trial period. The Silver Ghost PC was also auditioned, but offered far less improvement in SC that the other two. Start modestly and then move up the food chain, that is my best advice.
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.
