You cannot hear down to 5hz, you are lucky if you can hear 20hz.
Even if the player would be able to go down to 5hz, your headphones most likely are not, so you still wouldn't be able to hear.
If, and that's a big if, both the player and the headphones can reproduce 5hz, there's virtually no music that goes down below 20hz.
While on the topic of frequency response, the N8II is direct-coupled 90 per cent of the way, with only the input section of its discrete power stage requiring the use of coupling caps. Naturally, these coupling caps are of excellent quality, and the size afforded by N8II means they are of a certain value and footprint already.
That majority DC coupling should yield great extension into the lows on N8II. As @horatiu says, not really for you to hear a 5Hz tone rendered since that's as much to do with your transducers as the source, but to provide great phase response down to the lows. What passes through at 5Hz, or the N8II's -3dB point, passes through 20Hz and has an effect there.
We should hear the benefits of N8II's DC coupling, flat audioband frequency response and -3dB bass point much more tangibly through proper low frequency phase reproduction therefore. That means faster, tighter, more articulate and impactful bass and sub-bass (again, if your IEMs and cans can produce that).
