how can a line cord affect frequency response ?

Reb, you stated: The #1 factor by far is the type of conductor material the cord is built of. Everything else is secondary. Well, I agree but only to a certain point. If I compare my current cable, the Pure Note Paragon Enhanced with another less expensive pure silver conductor cable, I hear very audible differences. The Pure Note is detailed (silver effect), has good delineation of space and instruments (silver effect), is fast (silver effect), and has agile bass (silver effect). But it doesn't have the emphazised treble and harsh upper midrange of the typical pure silver cable. So I think it has also to do with the shape of the conductors (ribbon, round or rectangular), the dielectric material and whether the conductors are cryoed or not.

Don't you notice that it is always the engineering types who feel a need to justify by first principles the sound of his system to others when all he has to do is start the music? or do they think that all that talk before hand is going to make it sound any better? reminds me of the religious types who need to convince others to shore up their weak faith ...
Build your products with your theories, the heart and ears will be the ultimate judge. Theory and execution are two different things, only results matter.

The engineering types are the ones who give you your music Ronniekoh.
The marketing types love your paranoia.

Ronniekoh,

Why is it always the electronic ignorant that defend their "bat-like" hearing as gospel, and completely ignor the fact that ALL of their audio equipment was "ENGINEERED" based on decades of electronic research. You'd still be beating sticks together if it wasn't for engineering! Those silly idiots down at Pass, Krell, Levinson, Sim, Wadia, etc. Why haven't they gotten on board with all this vast PC knowledge on Agon? But I'm sure YOUR vast knowledge can run circles around their years of combined experience. Speaking of crystal-rubbing, UFO-watchin' "religious types"... Give us a break!

If you've visited their CES, HE and Euro shows during the last few years, you would find all these guys are using aftermarket high end power cords, interconnects and speaker cables.

Many use aftermarket equipment stands, isolation feet and other accessories as well. Anything to help with the sound.
