prof, re your reply to Dsper above: it's getting somewhat tedious to constantly read the same thing from you on cables. We all know how you feel, no need for constant reiteration. It's like saying over and over "I'm cognitively challenged and I expect everyone else to be too!" My wife and I, both professional classical musicians, have done the A-B test with numerous cables, amps, cd players and etc. There has never been any problem whatsoever in identifying different cables selected randomly from a list of say, 6. My wife (or me) selects a cable, the other person closes their eyes, opens them when the system is turned back on, and, no problem identifying the exact cable. Just like there is no problem hearing the difference between the Steinway 12 feet away from our 3.7s and the Thiels themselves. I have to say, thankfully, that's a small difference...
