Let me tell you my story wt Chinese clones.
Three years ago I bought some Chinbese Odin for $150 for a friend's system. Of course it sounded "okay", looking mysteriously close to the OEM. But the main body's plastic wouldn't flex as does pure FEP (Teflon). Indeed, it was cheap extruded PE...milk jugs! But I decided to explore further, buying a meter of the stuff and comparing jumpers made from it on my ref speakers, which had "enjoyed" Nordost SPM for decades. Couldn't pass an AB/X. So I carefully slit off ALL the outer cheap PE body, leaving a loose ribbon of individual plated Cu conductors that indeed had a very thin FEP cover on each. Huh...at least they paid lip service to that inner dielectric. Further, the coiled synthetic red "spacer" was identical to Nordost's. So I taped up these now-semi-naked strands and repeated the demos. Still no delta. Finally, I skinned off ALL the FEP and red spiral-wrap, gently and lightly taping the flat and naked array in the same geometry as original (and OEM). STILL no difference in sound. Eventually I bought some pure solid 20AWG silver strands, stuffed them in air tubes, wrapped as a star-quad (net 14AWG), using nice spades, and VOILA, all the solver-PLATED-copper crap I'd been listening to disappeared! Ok...this isn't a thread about conductor metals nor my ArgentPur startup, but about the extent to which a Chinese shop cloned Odin...except for the big bulky carcass. But to this day I continue to have disdain for ANY and all plated conductors.
