Topic: New ADI-2 DAC and Popping Sound

Probably not an ADI-2 issue, but thought I would ask here to perform my due diligence.

Purchased a new ADI-2 DAC and using out-of-the-box settings. My setup consists of the following:
ADI-2 RCA ----> KEF KC62 SW (RCA Input and LPF 80) ----> KEF KC62 (RCA Output and HPF 80) ----> Parasound A21 (Auto Sensing Enabled) ---- > KEF LS50 Meta

The problem occurs when I stop the audio signal, the LS50 Metas will pop,  ~10 minutes after the audio signal is stopped.

I have swapped all RCAs, power-cords, and speaker cables without success. Is there any suggestions or settings in the ADI-2 that could address the issue?

Thanks

Re: New ADI-2 DAC and Popping Sound

Is the Amp set to auto off ?

This is copy out of it :
Turn Off Delay in the Audio Mode
When the music (audio signal) stops, the A 21 will remain turned on for about five minutes. This delay prevents unwanted turn-off during silent passages in music or pauses between.

I guess the pop you hear is the switching off from the amp...?

Thanks for the reply, unfortunately that did not address the issue. The pop still occurs and before the amp goes into stand-by. I am leaning toward a bad KEF KC62.

Lastly,  I swapped the Parasound w/ a Bryston and same issue....

You can try to power down the ADI-2 DAC for testing.
A switched-off ADI-2 can‘t pop.

If you still get the pops try the same with the KEF KC62.
