I found two points of minimal contact between my interconnects and preamp power cord. I am not sure if the separation helped, but after a few more hours playing time the cable is sounding better again. I understand this cable design gives one a roller coaster ride during the break-in. Thanks for the suggestion.
JPS Lab Superconductor+ speaker cable break-in?
I have about 80 hours on my Superconductor+ speaker cables. I thought they were about broken-in, but now they are sounding bright again and less warm. The details, however are there and the dull phase is over. Can any one share their experience on break-in time for this cable and when it really settles down?
