I am not sure if I believe in cable cookers.......But some people do and who am I to argue (at least until I saw the price of commercial cable cookers are they kidding me?)
I don't know if the OP wants to burn in speaker wire or interconnects but I made a DIY interconnect cooker for free from some spare parts in my junk box and a little wire. I took an old RCA jack (with four plugs) and wired one pair of the RCAs to the speaker output from the amp and the other pair to some banana outlets so I could plug in my speakers. If everything is wired correctly when you plug in your interconnect it completes the circuit and you can play your speakers thru your interconnects. You don’t have to play it loud (and you shouldn’t) but even when you can barely hear the music in the room you are putting 100-1000x more power thru the interconnects than a line level output.
This is kind of hard to describe but I posted some pictures on the Polk forum a while back that should clear things up. Interestingly there wasn’t the least bit of interest there. Either they don’t believe in cookers or they already spent their $1000 for one.
