I visited my dealer awhile back &much to my surprise, he did use an aftermarket powercord for the motor of the tw raven one. i couldn't believe it, but it did make a discernable difference. Unfortunately i cannot remember the make of that pc he used in there. BUT it sure made the sound more quieter, clearer and more orderly.
