Hi
I was running the Dynamic range, Quality, Driver matching tests from
audiocheck.com on my HE6SEv2, SU-9n and this amp at max gain and max volume. On some playthroughs of the test there would be a click sound that would occur and sound would temporary stop. Did a some more test to determine what was happening as I never experienced this before (typically listen to my music on mid gain 9-10 o'clock). Then I realized that the amp was going into protection mode.
The headphones/amp still sound the same but I am worried that I may have damaged them.
Thanks,
