Can anyone comment on how well the ER4-S works with amplification?

I recently drove them with a stronger source and noticed possible driver "crackling" during demanding segments of different kinds of music...

Should a proper DAC/AMP be able to drive these without any sign of stress well above the threshold of pain? Yes I know i should be careful not to lose my hearing... Unfortunately for me I was an orchestral percussionist for over a decade and turns out that clashing or walloping away on cymbals a foot away from your ear all day long is not so great for them (measured loss of over 15% in both sides).

I understand that they are simply a BA design and that inherently this can be challenging, but would love to hear some first hand experience if anybody cares to share.

I'm also looking to validate the fact that my ER4-s are not broken...

I run my ER4 (not the S) off a Cmoy amp and it's sounds great. I also run them off a stereo receiver and have ran them off my Shiit Audio Magni 2 Uber. Not sure if that's helpful or not since it's not the ER4-S.
