Hi hifial,
i don't mean to start a war with you about the experience you have with MIT cables. Perhaps system synergy and individual taste do come into play when A/B between cables. I'm using electrostatic speakers which often project big sounds into the room, and maybe this work better with MIT cables when compared to HFC cables. I did A/B between these cables and the result is the strength of HFC gives a more coherent and balance frequency response. But it did not let me feel as much as "I'm there with the event " whenever i switch back using MIT cables. I do prefer the coherent sound of HFC but it is more relax and less "impactfull" as a whole. The MIT have a liveliness that make sounds fill with energy, more PRAT and its lower registrar have better impact than HFC. Btw, the comparison is done between Magnan MA and HFC ct-1E cables, so i maybe wrong given that I didn't try comparing higher range of HFC products. Base on my present experience, both these cables have more similarities than different on other sonic areas.
Anyway I'm mixing both cables in my system to fine tune the qualities i prefer and sometimes do swapping here & there for certain songs/album according to how the recording studio mix the materials.
