Mar00 Thank you for the technical information. It correlates with my experience: I tested a Dragonfly XLR cable once and I did not like it: it could not spatially resolve instruments, had a very narrow soundstage, and worst of all had the loudest, boomiest bass response I have ever heard from a cable (Monster close runners up). In short, the Dragonfly (the cheapest cable in the series, I think) had none of the features that attracted me to the more expensive cables in the NBS line. It seemed to me that the NBS virtues only became audible from KingSerpent upwards (with the analog cables). I am a little shocked at what your dissection of the Dragonfly revealed, and wish cable manufacturers used better quality cable for their purposes. As it is, the production costs for some cables are probably about 5 or 6% of their retail costs, the rest going into marketing and the high profit margins of the cable company and retailer, I suppose. Nevertheless, I still use NBS, and I still like them.
