Justubes2: What you are experiencing may just be break-in of the MC-0.5s, just like any other HFC product. With mine, I bought one and placed it in an unused AC outlet that also powers my HFC URH power conditioner. Initially, the increase in speed and detail were unreal, then the system sounded small and closed-in, then began a transformation into the usual expanding soundstage with great dynamics yet ease. I now have 7 of the MC-0.5s with 5 in the unused outlets of the power conditioner and there is a similar improvement when adding each one.
I still say the biggest improvement with these cables was when I added a single CT-1 interconnect. Adding more and moving up the line made an improvement each time but not as much each time as with the single CT-1. I would recommend getting one somewhere in your system and see what you think, probably at least as large as that of adding a magnetic waveguide. I now have 3 of the UR interconnects, U speaker cables, a URH power conditioner, a URH power cord to my phono stage, and 7 of the waveguides.
My experience is that the system will continue to benefit by adding more magnets, no matter what signal is subjected to the magnets.
Maybe Rick can develop a magnetic splitter. Or even a Pro version that costs $10K, lol. Or an E version of the MC-0.5. Or an electromagnet version of the cables. Maybe a magnetic hearing aid. The possibilities are endless.
