Hey Gordon, yup, thats exactly my experience as well. I changed Speaker and Power cables once together and heard details in songs I didnt even know existed until then, Particularly backround noises such as breathing, arm movements etc and I am very familiar with the songs in my system. Changed the cables back and did not hear these things. To me this set of cables gave me more depth into the actual recording, but I guess it was all in my head. hehehe
