Denafrips Pontus II Clicks Or Static?

There have been some who have reported clicks or static occasionally with their Denafrips Pontus II DAC units.  And there is a test measurement review of the Pontus II 12th on the golden sound website talking about the following:

"When DACs oversample, they can sometimes encounter a situation where the reconstructed/interpolated waveform goes above 0dBfs (the maximum possible digital value)."

"The Pontus 2 is susceptible to intersample overs, and unfortunately, in a particularly bad way."

"The Pontus 2 does not clip, but instead when a sample value reaches above the maximum, it ‘wraps around’ to the minimum negative value, causing a huge sudden transient which will be very audible and may appear as crackling/popping."

Has anyone with a Pontus II encountered this anomaly when playing CDs?  If so, can you elaborate about that?  I am aware that the Pontus II can be firmware upgraded, so if this is an occasional issue, it could be eliminated with an upgrade.

I have a terminator 12th edition fed from an Arces streamer via high quality cables. The source is Roon rock running on an Intel NUC.

I noticed random static / crackling sounds occasionally coming from one speaker. I tried everything I could think of to isolate the problem to a specific cable or component without success. I kept track of format / sampling rates NOS on or off etc but there was no correlation.  Turing the system off for a while sometimes helped but the noise invariably came back.

I read a post about dimmers and LED lights creating noise on the AC line so I tried turning off the dimmers while listening. Problem solved!!! 

I've been listening with a battery powered LED lantern until I can swap the dimmers for switches.  Sometimes it's the simple, inexpensive stuff that solves the problem. 

If you have dimmers and LED lights try turning them off.  Easy to do and it's free.
