I have no issues w/ IEC, using original PCs, in my Accuphase/Luxman setups. Using third party cables could lead to tolerance / bad / incompatible metal contact issues. To avoid it, either replace receptacle and plug by respectful brand, ideal one series, or hardwire device! It worked for me to resolve many critical studio and stage equipment power noise issues.
An IEC with grip
I am sure this has been discussed ad nauseum, but I have not found what I am looking for yet. I have built several power cables and bought a bunch, but I am consistently disappointed by the IEC plugs and their weak grip. I have spent some bucks on Neotech and Wireworld plugs and cords, and they frequently have to be pushed back in place. One of the cords that does have grip is the Classic+ that I received with my Puritan PSM156, that holds quite well.
Any suggestions? I know that I can improve things by wrapping the plug in tape to make it stay put, but my interest here is finding something with grip that will improve the connection.
