For example, with the IEMs plugged into an onboard Realtek ALC261 output, which has got a SNR close to 100dB, I can hear the SSD working..
You mean the SSD (wired on the same board?) causes EMI to sound card output or what?

IEMs provide an opportunity to drive 16 bit to its limits without damaging your ears, since a good portion of the baseline noise, that you have to live with in an usual listening environment, is kept out and you're feeding sound directly into your ear canal. Even with the maximum, pain-free listening level, recordings (and sometimes their recorded noise) seem to ascend from a floor of absolute silence - or the sound of my blood circulation (but my brain usually takes care of filtering out the latter).
Too bad I only have one ear canal compatible with triflanges at best.
What about a resistor to lower the sensitivity?
