Crane Song's HEDD series converters have earned a loyal following among professional recording, mastering, and front-of-house engineers. Now the HEDD Quantum ups the ante with several key upgrades. One of the most accurate converters we've seen here at Sweetwater, the Quantum features sub-picosecond jitter clocking applied to both the AD and the DA for exceptional imaging, a very open 3-dimensional sound, and highly detailed transient response. This is the same high-end clocking used in the company's flagship Avocet IIA DAC. Other upgrades include the addition of TOSlink optical I/O and six word clock outputs that let you use HEDD Quantum as a master clock while operating simultaneously as an AD/DA. Analog-generated dither is selectable for 16- or 20-bit.
