how can a line cord affect frequency response ?

Dpac,

Have you tried a "swifter" - IMHO it works better than spray and wash - the ionic charge picks up all unwanted vibrations....just remember to place them on your head while listening and change the pad every hour. Chepaest acpustic treatment on the market....and a well kept secret.

**I could simple squirt Spray and Wash on my speaker cones**

You'd better read the label first. If I'm not mistaken Spray and Wash only works on planars. Try Ortho-Cone and let us know. It is available in 4, 8, and 16 ohm solutions.

Thank you so much Audiofeil and TVAD, I knew there just had to be a simple scientific explanation lurking somewhere!
