Early in my pursuit of the high end, I had assembled a mixture of high end (amp) , revealing ribbon speakers, pretty good preamp and "wanna be" CD player and DAC. I decided to try some really good interconnects. Straight wire ... really expensive... like the early 80’s. I was really disappointed they were shrill and trebly sounding. I was really disappointed. I threw them in the closet. Played with copper and silver coated interconnect of much lessor value,
Years later my system had gotten many times better. I found the interconnects. Just for fun I plugged them in. My jaw dropped they were incredibly good... transparent... incredible bass and dynamics. Same story with a set of speaker wires. These were Transparent. Now passing all the frequency range through the wires was a good thing.
If you have a system that has lots of high frequency hash, high frequency distortion (fatiguing sound), with revealing speakers... then really good wires can make your system sound terrible. You want warm copper interconnects to cover up the deficiencies in your system.
Lower quality components have inexpensive power supplies and often have a lot of high frequency or noise floor you do not want to hear... so covering that up can be a good thing. This is why the Cardas strategy is to have their lowest priced interconnects and cables the warmest and least revealing and their highest end the most transparent. It is a brilliant strategy to match the cabling to the components. I used Cardas extensively early on in my pursuit of the high end.
All, my components are top notch and natural sounding... so now I want the very best transparent wires.
