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 an Ares 2 and a Pontus 2.  The only time I’ve had static or popping sounds was with the Ares 2 connected to a Bluesound Node N130 via USB.  Using coax was fine.  I then swapped out the Node for an iFi Zen Stream via USB and never had a problem after that.  Using that same setup with Pontus 2 and never had an issue.


I updated the firmware on both DACs today and it was very easy. Used a MacBook Pro and had no issues.  The instructions were very clear and easy to follow.

Both DACs sound a little better to my ears after the update.  Was definitely worth doing.
