If Frank thought that a different power cord would improve the sound of his products, he would have undoubtedly installed a different power cord. He is constantly refining the electronics. Surely, with this debate raging for years, Frank and his employees and his consultants have considered the validity of other power cords. These threads usually appear to me to be more of a debate about whether Frank decided, twenty or thirty years ago, that "a power cord is a power cord" and that he won't budge on this position despite some potential customers' preferences to choose their own power cords. Maybe someday, as an cost-added option, he'd install an IEC socket on his products to allow the user to choose his or her own power cord, although I suspect that Frank would begin receiving complaints about power cord-related problems, such as hum (if it were a three-prong IEC socket that was grounded to the chassis), compatibility, etc.. However, even though I don't personally know if different power cords would make any difference in my systems' sound, and I don't tinker with the specific components, I think that I understand that some audio enthusiasts would prefer to make their own decisions about the "accessories." With many manufacturers, the power cord is a user-replaceable accessory, and with Frank, the power cord is an integral part of the component.
