These are my new cables, I have never used these Nanofiber Interconnects. I do have the Manufacture Certificate for these cables.
The Nanofiber main strength is its exceptional midrange purity (we feel the midrange is absolutely as open as with the Indra - the flagship of STEALTH analog interconnects). The Nanofiber offers first class overall presentation: excellent speed, very good midbass and deep bass performance, sweet treble
The Nanofiber analog interconnect signal path is as straight and clean as it gets: it is free of any kind of solder or crimp because it is composed of very thin conductive carbon fibers (nano-fibers) which directly transform into the center pins of the proprietary STEALTH RCA or XLR connectors at the ends of the cables; the connectors are actually integrated into the cables. There is absolutely no metal of any kind in the signal carrying part of these cables. The return (shield) however is made of metal (multiple thin OFC strands) in both RCA and XLR configurations, and because of that, the Nanofiber cables are as silent and hum-free
there is one area where the Nanofiber actually outperforms the Indra: these pure carbon cables offer the least "listening fatigue" of all cables we have ever tested
The Nanofiber is the best choice for pure listening pleasure, If you like the Quad ESL loudspeakers, then you are most likely to prefer the Nanofiber to any other cable.
