    A system setting perhaps..

    Dear friend,

    Are you talking about the sound quanlity? Generally, Banlanced output has higher channel separation and steoro sense.
    The Q1MKII doesn't have firmware update.

    Best regards

    Yes, that's what I was expecting, but the 2.5mm balanced -to- 3.5mm unbalanced cable resulted in a significantly narrower sound-stage from the FiiO Q1 mkII's balanced-out.

    FiiO, do you know why this might be happening? If the connector was constructed correctly (R- R+ L+ L-), could it be that balanced-to-unbalanced is not possible without active circuitry?

    are you talking about losing soundstage when using the L26?

    I get the stuttering problem as well on my iPhone 7 playing music via Spotify premium and tidal lossless.
    I looked at the display and brightness section but do not see anything close to True Tone in there. Are you talking about turning off night shift mode? That changes the color of the screen during nighttime hours to be easier on the eyes I don’t see how it would cause this stuttering I hear that lasts 1-2 seconds usually once sometimes twice per song

    That setting is only on the iPhone 8, 8 Plus, and X.

    How should I configure the Fiio Q1mkii for best line out performance? Which gain level/volume pot position will produce the cleanest signal? Also, it would be nice to know for reference the vrms in that configuration.

    Dear friend,

    Let confirm you are using 2.5mm balanced port or 3.5 port first?
    2.5mm balanced-adpter for 3.5 unbalanced-3.5mm headphone: you could not get the same effect like using banlanced output.

    Best regards

    As I explained, I wanted to take advantage of the FiiO Q1 mkII 2.5mm balanced-out... to connect to my 3.5mm unbalanced headphones. I knew that I would not get the same effect as using a fully balanced connection, but the cable I used resulted in a significantly narrower sound-stage compared to using a standard 3.5mm cable from the FiiO Q1 mkII unbalanced-out.

    I was assured that the 2.5mm connection was constructed correctly (R- R+ L+ L-). Is balanced-to-unbalanced conversion/transmission not possible without active circuitry?

    This is a very slick design :L3000:

    If you are connecting an unbalanced cable to a balanced source you might short circuit the amp. Not a good idea. Garbled sound is the least of your problems. If you have a balanced cabled headphone you can connect it with an adapter to unbalanced output but not the other way around. Balanced output has to always be connected to balanced down the line, otherwise you are combining the different grounds and short circuiting them, which can even damage the amp. Don’t do this. Recable your headphones or buy a balanced cable for them, it’s the only way.

    Everyone should be careful about using unbalanced cables with a balanced port and i reckon manufacturers should issue a warning in the package for such devices. The result will be a fried up amp.

    The cable I have was custom-constructed: the end connected to my FiiO Q1 mkII is balanced (TRRS) 2.5mm ; the other end is unbalanced 3.5mm (to connect to my headphones). The sound is listenable, with a much narrower sound-stage compared to using a double-ended 3.5mm cable with the FiiO's unbalanced-out.

    Even if the 2.5mm balanced connection was constructed correctly (tip to sleeve: R- R+ L+ L-), is balanced-to-unbalanced conversion possible within a cable?

    No. Some players have short circuit protection though. But what you are trying to achieve does not work. There is already an unbalanced connector in your device. With any unbalanced equipment that is the one to use. I repeat. Do not use unbalanced equipment on a balanced output.

    Edit: whoever created that cable should have told you. It only goes the other way unbalanced to balanced output (though it doesn’t make the signal balanced).
