I have dac/cd player, pre-amp and power-amp all powered from Powerplant 5.
Interlinks are unbalanced.
I have a audible noise in my (passive) loudspeakers, even with the dac section not connected to my laptop.
The speakers are dead silent when the dac/cd player is disconnected from the P5. So the problem obviously lies with the dac/cd player.
The question I have: can I rule out groundloop as possible cause, assuming that the P5 provides a single ground for all components connected to it (as in my set-up) ?
