Rsbeck: The measurements that you initially referenced showed roll-off starting at appr 22 KHz if i remember correctly. This frequency is based on an 8 ohm load. Using a 4 ohm load, roll-off would occur at half that frequency i.e. 11 khz. At a 2 ohm load, roll-off would occur at appr 5.5 KHz. With a 1 ohm load, roll-off would occur at appr 2.75 KHz.
Given that impedance varies with frequency on most every speaker known to man, the associated roll-off's and phase shifts are quite audible when one has both good listening ability and a reasonably transparent system. It should be noted that there is a BIG difference between having "good hearing" and being a "good listener". For the record, i have several sets of speakers that drop below 2 ohms, hence my concern over such matters.
Obviously, the zip cord only works "acceptably" with a theoretically non-reactive speaker that maintains an impedance of 8 ohms or higher. It should also be noted that not all zip cord is of the same inductance level or nominal impedance, so these figures are based on best case scenarios. As length of the cabling is increased and / or the inductance climbs higher, the effects will become even more pronounced and severe in amplitude. The fact that the nominal impedance of the cable is 100 ohms or more, and will negatively effect power transfer characteristics from the amp to the speaker, is true regardless of the length used.
As to what you've told me, i forgot all of that. If it was true or factual in the least, i would remember it. You keep painting pictures but you leave out the most important details i.e. the ones that discredit your point of view and the message that you are trying to promote. The fact that i've refuted your past arguments using your own reference materials shows that those you rely on to do your homework for you also paint "half pictures".
Like i said, put your money where your mouth is. If zip cord works as well as you've said, you'll hear no difference, can continue to enjoy your system as you know it and can actually put a few dollars in your pocket from the sales of the "snake oil" cables that you're currently using. Until you actually do as you suggest that others do, you will be thought of as the boy who cried wolf. Over and over again. Sean

PS... Nelson Pass demonstrated that different cables affect power transfer, transient response and even the ability to make or break a system in terms of operating or shutting down simply by changing speaker cabling. He did so 25+ years ago and that evidence is still posted today. The fact that Nelson does not market ANY type of cabling and only did this because of the differences in how amplifiers were responding to specific loads doesn't seem to phase those that wish to promote a specific agenda i.e. that such things can and do alter what we hear and how the system responds.
