I see a bunch of HUGFEN audio cables for auction on ebay at pretty resonable prices. Does anyone have any experience with these cables? I went to the manufacturer's website but couldn't find any info on them, or even any way to contact the manufacturer. I'm looking at their quad shield zero noise cable (DXZ), but I can't find out if it's coax or twisted pair, what kind of shielding - foil? braid? Help! I think these might be designed for car audio. Are they suitable for home audio?
