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 had this issue, but isn't frequent enough in nature to be a problem. At least to me anyway. The noise I get from my Pontus ll is a extremely soft low level pop, which happens maybe twice during a 3 hour listening session. While I would appreciate dead silence, it isn't that offensive to bother me. Pops, clicks, and snaps from vinyl are FAR more annoying than this.

@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.
