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.

@All

i just finished this entire thread and boy my head hurts.  The only reason I landed on this was after listening to Audio Science’s Amir explain the jitter, Dac clock vs source clock, pll and how that works and noticed he had not tested the Pontus ii, so I went a googling.

i purchased a Pontus ii 12th Anv. Which arrived today and is sitting boxed in my basement.  Now I’m afraid to open it 🙄.  Seriously, it’s replacing and old Burson DA 160 which I’ve loved over the years, but it seems to be choking on the new Eversolo A8.  Anyway, I am coupling it to an Audiophonics HPA Purifi D class and will report back should I hear any of those pesky pops.

Are you using the same cable, or different coax cables. Try switching and see if the problem switches.

I know this post is very late on this topic- 

The Denafrips POP

I purchased a used Pontius II 12th yesterday. swapped it into my system with the Pontius feeding into  Backert Labs Rhumba 1.0. I was listening at a low db level evaluating the sound and about 5 minutes into the listening  session I got the pop. The pop blew out something in my preamp where now I have a low volume, 100hz oscillating sound in both speakers of my system and will need to send the preamp out for repairs.

Anyone else have a pop like this?
