As I posted in the previous (currently closed) thread about these cords, I bought an ESP MusicCord to try to hear for myself if it would make a difference. I could think of no reason why an AC cord should make a difference, but wanted to try. I bought the $129, 2-meter cord. Ordering is easy (he takes PayPal) and shipment was prompt. I must say that this thing is impressive looking -- it's massive. I've been testing this at home (where I expect to hear the greatest difference). Rig is a Fender Roscoe Beck IV with TI rounds -> Spectraflex cable -> AI Focus 1 Series III head -> EA VL-110 cab. Mids and highs up all the way on the EA and the treble on the Focus was set to about 3:00 -- brighter than normal; I was listening for changes in "harshness." Tone control on the bass was almost all the way up. This was not a blind test: I was switching between the MusicCord and the stock AI cord. Nor was this test objective; it was just me and my ears. I have to report that I hear no difference between the stock cable and the MusicCord. The level of background noise from the amplifier sounded the same with both power cords -- low but audible if you're close to the cabinet. Tone sounded the same both ways. I like this rig already, so there's nothing I specifically want to improve. I was skeptical, but not specifically predudiced one way or the other. I'm also no Eric Johnson -- no "golden ears" boy. I just do not hear a difference in this limited test. I'll probably hold onto the cable. It will make a good conversation piece and Michigan can use a little stimulus money (although those bastards from Michigan State beat my UConn yesterday).
