Hi all,
I've designed and built a combination DAC and headphone amp that I'm having trouble with. The DAC sounds great for the first few seconds when used, but after 5-10 seconds the audio quality seriously degrades to being unlistenable. It's basically a grubDac I changed the power supply on-I don't know why I'd have these problems using a proven circuit. Any insights?
Edit: It's not on the schematic, U6 is Wolfson WM8524

Nevermind. The batteries were dead. It’s always the simple things.
It sounds great. If anyone wants more info let me know, I’ll share board designs and such. Designed to fit in a tiny Hammond 1455C801 case.
