some interesting concepts explored here - Cables knowing things and whether we should trust out brains etc or Do I need a psychologist to help me choose an interconnect?

For what it's worth I dont accept that cables have memories or have achieved a level of conciousness - for instance my cables dont mind what kind of music I play and I havent talked to them for ages. I am sure that real differences probably do exist between cables ability to accurately carry a complex AC signal and that losses probably occur in all cables of aspects of the AC current that they are carrying. This results in a small but (by some peoples listening anecdotes) appreciable change in the sound produced by the transducers. As I age I am told that my ears are not as great as they used to be so the next real break through in hifi will probably be an implant and shee hifi perfection - I just hope the musicians can lift their game too!
