If time permits, I test different hifi components every now and again. Cables are a hobbyhorse of mine. I've tested a lot of different cables over the past few years, from old established cable manufacturers like Transparent, MIT, Wireworld, Audioquest, Siltech et cetera. Especially lately I have dealt extensively with grounding systems and currently well tested cables such as Masterbuild, Jorma, Synergistic and Higher Fidelity cables.
In my hi-fi chain, the Higher Fidelity cables also seemed at first a little reserved. Especially these magnetic cables took a lot of playing time and after at least 200 hours they play very dynamically. The Higher Fidelity Cables as well as the Master Built Cables belong to the cables which impressed me very much. In the disciplines of musicality, naturalness and soundstage these cables are almost on par with the Schnerzinger cables.
With the Higher Fidelity cables it is important to use them as a complete system otherwise much of their magic can be lost. As I am currently working intensively on grounding systems like Tripoint, Nordost, Schnerzinger, Entreq etc., I can already say that these massive sonic progresses cause my audio system. I advise anyone who does not have a grounding system to test one. I wish you a lot of fun listening and give the Higher Fidelity cables some more time, it will be worth!
Someone on Audiogon was selling two pair of the High Fidelity Ultimate Reference RCA interconnects. They were a couple years old, and fully broken in. He let me audition them in home and they were fantastic. After my recent cable rolling adventures, these HF UR interconnects were my second favorite cables behind only the top of the line Master Builts. And honestly, they aren't far off. The Mastur Built were a bit better in micro dynamics and had a slightly fuller (if not rounder) tone. But I also can't complain about the High Fidelity Ultimate Reference in either category. So, with the enormous price difference, I'd be more than happy to "settle" for the High Fidelity.
Interestingly, though, the owner also told me that he'd recommend avoiding the High Fidelity speaker cables. He found them rolled off and unfixable with break in. Nothing like the HF interconnects. He'd also tried a special low capacitance version from Rick Shultz, and still didn't like them. Perhaps it was system related, but he recommended Schnerzinger speaker cables over the HFs.
