From the seller

Quantum clocking is the same sub pico second jitter clocking that is used in the Avocet IIA DAC In HEDD Quantum, the sub ps jitter clocking is applied to both the AD and the DA. The result is very good imaging, a very open 3d sound, and very detailed transit response, it is very accurate. Optical in and out have been added, toslink HEDD Quantum as a master clock There are 6 new WC outputs that allow HEDD Quantum to be used as a master clock at the same time that the AD and DA are being used In addition to the new AD, DA, Clocking, I/O and WC outputs. HEDD Quantum still has the same great DSP emulation of Triode, Pentode tubes and Tape emulation Operational modes allow the DA and the AD to be used at the same time, at different sample rates. In the DIGI setting the unit will run digital in from one of three sources and output on all three digital outputs and the analog output at the same time. In the ANA mode the input is analog and it outputs on all three digital outputs and the analog output at the same time. Dither, which is analog generated, is selectable for 16 or 20 bit The AD, DA and ASRC chips are the high end AKM 32 bit parts, coupled with proprietary analog filtering and clocking
