What is coming out of your DC/Dc converter?

I've reflowed all the joints but they look ok, all of the 3.3v pins on the pcm2707 read 4.75v |
Edit: I even read 4.75v across C8 with no Reg101 in place, the DAC also works without Reg101 installed!?! :| |

Anyone else had this? I have had this problem with my Guzzler DAC for a very long time, I assumed something had gone wrong but I couldn't be arsed to open the case up. (The Emu 0404 in the same PC is fine.) |
