Every system is different, maybe in your system 2 harmonic tech cables can work together.
Harmonic tech clock cables need long time to run in. The first 72 hours seem to sound good on vocals but less separation between instruments, after 72 hours vocals will start to sound thin, but separation will be better and better. Everything will come together after 300 hours, you will have airy vocals with good instrument separation then.
My system has x3 purple fuses so maybe that helps a little with the mids, I can also agree that my first Harmonic Tech Copper cable changed a whole lot, it became far less fatiguing at Squarewave and was a must have when used in my X26 Pro. The separation and dynamics boost is starting to become really apparent with my second cable fed to my U18, it's quite interesting. Maybe a week later and all harshness will be rolled off and gone and what I'll be left with is heaven.
