Reference High Resolution USB
Like all our cables, the Reference High Resolution USB is based on the results of our in-depth research into cable design, which began in 1995 and was recently detailed in the updated Genesis Report. This report sets out the design principles we adhere to and which have led to the development of a range of cables that represent the ultimate expression of sound through science without compromise.
Every QED cable in its range is based on the flagship model and, although they may be influenced by price, size or ease of use, each one retains the original core characteristics of that model. This gives even the entry-level cable in each range a sonic advantage over similarly priced competitors. The Reference High Resolution USB is QED's state-of-the-art offering and, as such, represents the culmination of our understanding of this complex cable application.
