Try this. Leave the listening room and have somebody swap your Special Fuses out (or not) and replace them with un-special fuses like something from Littelfuse or maybe Bob's Discount Fuse House…come back and listen to your rig…do this again a few times to see if you can tell when the fuses are different. I'm assuming the Special Fuses don't lose their "broken in" status when briefly removed (damn…there goes 170 hours!)…note the results. Did cello's feel less cello-like? Did the soundstage seem less soundstagey? I doubt any Fusers are going to do this experiment, but hey…you could claim to do it and fake the results to gain credibility among Real Audiophiles. Win win. Also, paint Jujubes silver and replace the tiny SR "transducer" dot things with them and try this experiment again, although this version may be flawed when it's discovered that painted Jujubes work really well in that role. I just think the damn things stick to my teeth too much.
