I bought an Aune T1 (Mk1) DAC a while ago and was very happy with. Then one day it just died. The headphone amp function still worked, but the USB DAC wasn't recognised any more, I tried different cables, different computers etc.. Anyway to cut a long story short, I returned it to China directly to Aune. They were good about fixing it and returned it. They mentioned they noticed I had an old chip and they replaced it with a new version. I'm not 100% sure what chip they were talking about. Anyway, I have it back and its working again. BUT, now the gain is very low. Whether using RCA out (to my Crack), or via the headphone jack, you have to turn the volume up very high to get acceptable sound levels. I have the gain toggle switches set to maximum. It used to be MUCH louder. I really can't bring myself to send it back again.. the postage alone is starting to outweigh the cost of the unit.
So this leads to my question. I am tempted to open it up and have a look inside. I know this will void my warranty, but is there anything you gurus out there would look for that might cause the gain to be so low? In my simplistic mind, I'm thinking I could remove a resistor or something... is this wishful thinking??
