A quick solution is increasing the effective impedance of the headphones with an adapter. There are a number on the market both as plugs and pigtails. When I use low impedance headphones on the phone jack of my preamp (Anthem Pre2L, 4x6922) there is a bit of hum and hiss. I have a pigtail adapter from Ultimate Ears that I think adds another 125 Ohm effective load (https://pro.ultimateears.com/adjustable-ambient-filters-248.html).
The result is that the noise is eliminated. I also use it for computer listening through an AudioEngine D1 as it gives the volume control a much greater range of adjustment.
