Am sorry to hear that..but its weird though..i had 3 toxic cables until,now and two adapter cables..and not one had the issues ur talking about..but i have to admit..i didnt had the silver poison..my cables were (and still is) all black widows..
.i do know he improves his cables regularey..so i dont know how old the cable is u bought second hand..maybe its an older revision? and are u sure it was built by toxic cables itself? If i am not mistaken i understand some people buying the raw wires from toxic cables and then making the cables (sleeving etc) themselves....
Oh well..i do hope u will find the right cable for u....as microphobics is something i cant stand also..thats why i asked toxic cables to sleeve my last cable with tough black nylon sleeving, instead of any other flashy sleeve.
BTW norse cables is also a brand i know make excellent cables.
