Last night I was fooling around and I noticed that when I turned the volume all the way up on my Yaqin 13S I could hear humming through the speakers. I traced the problem to the interconnects. When they were removed, no humming whatsoever. So after a little research I decided to build some shielded interconnects out of some TV coaxial cable which I had on hand. This particular cable had both the foil and wire mesh shield which according to what I read is the best version to use for this purpose. To make a long story short, it worked perfectly, no humming. The cost was negligible, almost nothing and it only took a few moments to make.


It also had an effect on the sound, which to my ears were a nice improvement. Oddly, they replaced some very expensive interconnects and I like them better. I think I'll be selling my “old” interconnects.
