PS audio ultralink II dac distortion


Hello All,

   I have a PS audio ultralink II dac that has suddenly low volume and distortion from both channels. I hooked up another dac and no problems. So I am sure it is the ultralink. Anyone know what it could possibly be? What I should I have it check for? Any advice would be greatly appreciated.  Thanks

call PS audio they have some of the best customer service around I'm sure they will help you through your issue.
Thank you for your response. I did call them and they stated they did not service these dac because they were made at a time when PS audio was sold and owned by someone else. So they could not really help with this because they have not designed or build this PS audio line. 
I have a PS Audio DAC III Digital Link,
it sounded great when I purchased it 2012 now it’s
sounds Too bright with all formats coax SPDIF,USB,and Toslink.
a new DAC coming soon Wyred 4 Sound 2v2.

I would be weary of stuff made by Wyred 4 Sound, their Remedy reclocker for instance does absolutely nothing to the signal.
