Sabai, try removing the magnets that surround your cables and system. You will find there is a veil and constriction that has been lifted from the sound.
Years ago I used rare earth magnets in various patterns to surround the connectors of a power cable I had. I also had a coaxial digital cable by a manufacturer that has magnets in the RCA itself.
When these items were first plugged in, it was like a void of silence, a huge improvement, such an exciting gain in performance, but as time went by, literally only a few days, the sound would continue to deteriorate and the magic was lost to the point the system started to sound negative compared to when the cables first went in.
I was mystified as to why this happened. Then I read a review of Lotus Audio magnetic power cables by Marty DeWulf of Bound for Sound. The exact same thing happened to him, those power cables were the best he ever heard, only initially, and then the performance deteriorated over time.
I asked Mr Magnets, Rick Schultz, why this happens with passively applied magnets, he had a technical explanation I will try and remember; the magnets initially create a magnetic field that the signal can pass through more freely than before, improving the sound. But over time the magnets start to magnetically charge the surrounding cable connectors, the wire, component sockets e.t.c in an uncontrolled fashion, making performance deteriorate.
After this experience with magnets, my initial concern about HFC was it would deteriorate, but its the opposite, it gets better and better with time. This must be due to using the magnets as a part of the signal path itself, rather than externally interfering with the signal.
