Can DirectStream Memory Player play SACD with AES? Would he be a DOP if he could?  
And does anyone know if DirectStream Memory Player or PS Audio PerfectWave transport CD can change the voltage?

As far as I know the DMP required i2s via hsmi to satisfy the Sony copy protection and allow the DSD to be transferred to the dac via hdmi.
