Headphoneus Supremus
Unfortunately my X5 II is currently in China for scroll-wheel repair – with uncertain return date. From what I recall the equalizer is still active through the line out (it certainly is through S/PDIF out), and going by the X3 II I would say the output impedance is higher than with the headphone output, resulting in an altered tonal balance with the low-impedance Andromeda, while the HE1000se sounds quite similar via both outputs.It seems that I can't fix the headphone socket - the line/coax digital out is working fine. Normally I use that for my DAC/AMP (FiiO E12), so I still can use the FiiO X5-II.
But without the DAC/AMP I also can use it directly with my headphone (there is a setting to enable the volume on that output). But what do I miss when using that port? Only the in-line headphone control? I have read that it output's an unamplified signal - so EQ settings etc. are not working?
