Ferrite Claps

I have H.T.Prosilway MK2 interconnects and was floored by them.I wanted a new power cord for my preamp outboard power supply so my dealer sent me a H.T.Pro-AC11 to try.Well,not floorded with these.Heard no difference over the stock cord.I had at least 200 hours on it also.Best place for power cords is source components(usually) As mine is a turntable I couldnt try it there so back the cord went.I was very disappointed!!

My opinion is with the higher priced power cords they have alot of good EMI and RFI shielding built in.Chokes probably aren't required and Im not even sure if the chokes work on my stock cords anyway,but I still use them since they are so cheap at Radio Shack.
