Hehe
From Schiit Audio
Modi:
Output Impedance: 75 ohms
Your 558 have mostly 60Ohms, with the middle bass having 600 Ohms,
Kind of very simplified explanation is that Modi puts just half of the power into not mid-bass section (half of the energy is eaten up~=-3db); while the midbass (~100Hz) gets very large part of it (almost all, 0db change).
Your integreated soundcard has most likely 1 Ohm meaning that almost 100% is send to the heaphone
You can check the chart on personalaudio.ru.
I have a similar situation with Beats Mixr when on xonar stx vs realtec (they have more bass on STX).
The situation with hd600 is kind of diffrent because by default they have in most of FR 300 Ohms, (but the hump is also 600 Ohms(.
