The advantage of the Class A PSU for the clock:
         Except the Jitter, there is another important factor effect the digital audio sound quality,  the Phase noise is . Through the practice and test , most 3 pins PSU-ICs are the worst PSUs for the clock because they've feedback loop circuit cause the phase noise increase , even a simple discrete PSU (built by  a transistor, a diode , a resistor and a cap) had better perform.
         The Class A have better perform result because it had very high input impedance and low output impedance can avoid power disturbs, the no feedback loop circuit avoid phase noise increase.
