i doubt this probably after 500hours for small can and 1000-2000 hours for big can, they will become "statble" and sound as it should be. no matter what kind of music you are using to burn or using special signal like pink noise, red noise...

the difference is rather noticeable at the beginning of the phase, after that, all come to one end .

the signature actually much depends on the material of cable. if PcWork use silver one, it will enhance the mid and treb, so maybe feel brighter. in constrast, if copper (silver plated ) will generate extra bass . just wonder if we can mix them, so we can enhance all range of freq . it has to wait for PcWork .
