Distortion using Node 2i as streamer with Denafrips Pontus Dac


Hi all, has anyone had trouble with distortion when coupling a Node 2i streamer with a Denafrips Pontus Dac? 
I have tried using an optical, coax and usb connection from my iMac and after about a half hour to an hour I get distortion from both left and right speakers. 
On Alvin Chee’s recommendation I turned off the “Audio Clock Trim in the audio setting of the Node 2i but I still get the same distortion. 
I did have success being able to stream cd music from an Oppo CD player using an optical cable. 
Has anyone experienced similar problems? Any luck getting it resolved? I’ve only had the Pontus for a few weeks. Any suggestions would be helpful. 
I am thinking about trying another Node 2i to hear if I have the same problems.

Hey guys,

I should chime in to let you guys know that I am actively assisting @wgs57 to troubleshoot the issue. 

Statistically, the failure rate of the DENAFRIPS DACs is low. We ship hundreds of DACs monthly, the failure rate is less than 0.5%, i.e. 2 out of 500 DACs.

We don't rule out the DAC is faulty. We work with the owner to run through a few tests to identify the root cause before deciding the next course of action. Instead of jumping into the conclusion that the failure is on the DAC, of which, may wrongly diagnose and cost everybody more time and money unnecessarily. 

A classis example recently was, a customer received the Ares II notice annoying ground loop hum in the system. We run through a few tests by removing the earth cable, trying to break the loop but the hum persisted. We decisively (wrongfully too, sadly), ship a new Ares II to the customer. The new unit hum too. After a few more in depth rounds of troubleshooting with the customer, it turns out to be the subwoofer and AVR integrated in the stereo system was causing the audible hum at the loudspeakers. 

Nonetheless, please be sure that we are here to help. We standby our warranty and customer services. 

Many thanks.

Yours sincerely,
