So I have to skip this option too. Sorry for the effort you put in the extensive explanation but it might be useful for others to use. <br /><br />The Centaur boosts a 2A against the LT3045 with 0,56 per rail if I stand correctly. As I use the sidecar connected to the Placid of the DAC I’m in doubt if the LT3045 is capable of providing sufficient headroom? The power to the XO an AVCC is divided dough. <br />To do it the best way I need 3 seperate PSU’s per DAC don’t I?
