Kira, I discovered something while changing my main rig around. I went with the Oppo as a CD transport for a short while. When I switched on the Onkyo nearby, there was a slight hesitation. I am guessing that the power drain affected the power to the transport. That never happened with my Jolida transport. I think that having a transport with a solid case that is vibration resistant, and a power supply that exceeds your needs may be important. All I know is, I put the Jolida back.
