Unfortunately both units are defective or at least they do not operate in my system.....
When I connect them to my DAC the signal gets dropped out intermittently with a really loud popping noise
I tried with RCA connection (both low gain and high gain), XLR connection, volume bypass, etc.
Then I tried with a different amp and my system just works fine
The issue is only happening with the two A7 Mono amps
See a video about the issue here:

You can see that the signal is intact (DAC showing sample rate) and when the amp is switched on the signal gets dropped out
Now let's see the same with my Fosi V3 Mono amp:

No issues, works perfectly
I have opened a ticket with Audiophonics, let's see.....
I am really disappointed I have to say
@3eaudio for your information, not sure if you have seen this type of issue before
