In my system they are incredible. I have Reference interconnects, reference speaker cables and the Diamond power cord. In my 50 years in this awesome but spendy hobby, I have had many many different cables from cheap to $8400 power cords and the swisscables have had much more of a positive game changing effect on my system than any I've ever owned. I will never again buy any other than swisscables. Next move will be to save for their Diamond speaker cables!!
