    Hey Brooko,

    Thanks so much for the testing results. Well i’m Listening to it now as i type this and suddenly, the gain switch does nothing on the X3iii. I swear it changed the volume when I tried it yesterday. Weird. Now, i can’t replicate that problem, so i guess one problem is solved, i hope.

    I don’t hear clipping or distortion now as well. Could it be the amp needed to break in or something?
    Really have no clue. Suddenly now i’m getting nice sound from it. And regarding the volume setting, if i turn down the volume on my A3 to 2.5-3 as you suggest, itt’s really very soft. I Don’t like listening at loud levels either and always practice a safe listening Level. For me, 4.5 is ideal and for some dsd recordings, i need to turn it up to 5 or 5.5 to get it loud enough. Again, I stress, this is a very safe listening level, not at all loud. Very comfortable and i can still hear some sounds outside.

    Another question, the setting for LO fixed volume and volume adjustment, if i choose fixed, it’s at maximum volume of 120 right?

    Don't worry - it just shows how powerful the brain is. I've lost count of the number of times I've tweaked an EQ to get it just right, and then found that I didn't have the EQ actually engaged :) It just shows us we're human. It shouldn't be the amp breaking in (I've personally never experienced anything like that) - but if you genuinely heard clipping then who knows - maybe it was the caps warming up. Its good that you're getting the right sound now anyway.

    Re the volume - it'll depend on what you were listening to (how it was recorded), but I really do suggest getting an SPL meter at some stage, and actually measuring the output. At above 80 dB for extended periods of time you will do damage. You can train yourself to listen quieter, and after a while it becomes natural. It's hard to judge when I don't have the same headphones - and I could have it wrong. Thats why it would be good to know for sure. the problem with hearing damage is how often its permanent. I have tinnitus permanently (an accident ~ 15 years ago), I can't hear simple silence any more. Its amazing how much you miss the simple things when they're gone.

    With the line-out, don't think in terms of volume - thing in terms of constant voltage. The line-out outputs 1.9 Vrms (10 KΩ/1 kHz).

    Gee, that’s a great explanation buddy. I can assure you the sound levels i listen to are not loud at all. Maybe my files have a softer volume throughout.

    On the line out setting, would it be safe to say the fixed volume setting is bettter than volume adjustment?

    It really depends. I have a portable valve amp, and if I run any of my FiiO's at full line-out into the HVA, it overdrives the tubes (into distortion), so in that case, the variable line-out is brilliant. I just drop it to about 75% and problem solved. But most SS amps should be able to handle the fixed line-out with no issues.

    Great, thanks buddy. You’ve been a great help and thanks for being patient with my questions. God bless!

    I’d like to report what I believe is an issue with the X3MKIII (running firmware 1.1.4) concerning its handling of external playlists.

    Playing a track from an external playlist, the track is identified as 174/263.
    Switch off.
    Switch on.
    The track resumes playing but is now identified as 2/36.

    It appears that the unit has ‘forgotten’ it was playing from the list and has reverted to playing from just the album containing the track.

    Is this a bug or intended behaviour?
  7. Brooko Contributor
    Good catch David. Confirm it with mine too. The playlist is essentially just a link to the album and track - and it appears that if turning off it's resuming the track on the album, and not the playlist.
  8. David_L
    It doesn’t appear to be limited to external playlists.

    I just tried playing by Artist > selected artist > All Tracks
    Switch Off, Wait, Switch On
    Track replay resumes but from the Album only, not All Tracks.

    Does anyone know if this “feature” exists on other Fiio models? Or is it new to the X3III?

    Thanks for the kind feedback. We will report those issue to our engineers and try solving the issue in later firmware. Sorry if bringing inconvenience to you.
    Best regards

    What speed issue was that?
  13. FiiO
    Thanks for considering our product. Maybe you can have a try in the local store first before making a decision. Hope you can get the one you like. We will go on improve our X3MKIII as well.

    Any comparisons to X5ii?
  15. Dobrescu George
    As an overall device, X5ii should be a bit better, 2xmSD slots, more smoothness in operation, etc.
