16. Can the Q5 work with K5?

A: Yes, the Q5 can work as a DAC for the K5 by docking way. 
Please be noted that, when they work together, only Q5's USB and Bluetooth connection can work, but NOT for Coaxial/Optical/LineInput.  Moreover, when the K5 powers on/off, the docked Q5 will NOT power on/off in sync.
