“Providing significantly greater performance than any similarly or lower-priced
alternative, and undoubtedly one of the best computer-audio DACs now available regardless
of price, the QB-9 is a watershed component in this watershed year. It is what it is,
nothing more, nothing less: a USB DAC unabashedly focused on making the best possible
computer-audio sound for the least amount of money.”
