I had the same thing in my email today too... Strange thing is I believe it to a certain extent.Years ago I remember swapping cables when I had a tube preamp, and a SS amp... There was a night, and day difference but I believe it had to do with the input and output impedance of the equipment. I say this because when I got my Classe Audio DR6 preamp, and DR10 amps it made absolutely no difference what cables I used. The Dr6 had an output impedance of less than 1 ohm. I do find it hard to believe that with today's SS equipment though that there would be any difference at all with a cable unless it was made poorly.
