What do you all recommend as a nice over the ear headphone to pair with the X1? (~$200 range)
I have a theory about the equalizers in the X3 and X1. When the equalizer is on in the X3, the volume reduces. When the equalizer is on in the X1, the volume doesn't reduce. I also notice that the sound of the X1 is similar to the X3, when the X3's equalizer is on, with the custom setting being "flat". Is it possible that the X1's "EQ off" setting actually secretly has the EQ on, with a flat setting?
Unfortunately, there's something about the Equalizer in the X3 and the overall sound of the X1 that tires me during long term listening. I can listen for hours to the X3 with the Equalizer set to "off". I'm just trying to figure out what's going on.
I've noticed when I use the equalizer on the X1 that the volume level does not go beyond 88 out of 100. I am still on FW 1.1, do the later versions fix it?

1. The equalizer is off when it is off on the X1.
2. When enabling the equalizer in the X1, instead of just dropping the digital gain to make digital headroom like in the X3, it also raises the analog volume to compensate. Thus volume 88 with EQ on corresponds to full analog volume with EQ off. This behaviour also proves that the EQ is really off when it is off.

Is the frequency response of the Fiio X1's headphone out is up to 20kHz?
Does it mean that playing music above 44.1kHz sampling frequency won't offer any benefit to audio quality?
Frequency response and sampling frequency are different thing, but basically yes - higher oversampling frequency benefits are debatable and there's also the possibility that the perceived differences might actually be detrimental.
Yup, that I know
What I'm curious is whether the X1 headphone out can actually output more than 20kHz.
My understanding is that the filtering process is more gradual with high sampling rates. So that is the source of much of the sonic benefit on hi Rez files. And the 24bits provides more headroom and lower noise floor
