Okay, now you're confusing me. So here's the above information a little more verbosely, let me know if it helps.
Headphones are neither single-ended nor balanced. Those are the shorthand terms we use for describing how they connect to amps, but they don't mean quite the same things that are meant among active electronics designers (the people making the amps, DACs, etc.)
Every working speaker circuit needs two wires between amp and speaker: one + and one -. Stereo sound requires two circuits: One for the left ear, one for the right ear. Your headphone has two speakers, thus two circuits.
"Single-ended" means that the cable or plug will connect left and right channels through the - line.
"Balanced" means that the left and right channels never touch*: There has to be four wires between amp and headphone, and requires four connection points at the amp.
You can't use your Q701 with a balanced amp because the cable only has three wires in it: The - is common from the amp plug to inside the headphone shell. If you make an adaptor to use with your ALO, you'll bridge the channels, and bad things might happen**. That's it; Short of cracking the headphone open and rewiring it, you will never safely use it with a balanced amp.
If LFF is making you a headphone, you can order it with balanced wiring and this is totally okay.
*("Balanced" actually means that there are two amplification circuits per channel out of phase with each other. Speakers are passive devices reacting to an electrical signal and will react exactly the same way to exactly the same signal regardless of whether the device providing it is single-ended or balanced. "Balanced" headphone wiring only means that your headphones are wired to ensure the - does not get bridged; your average non-balanced-electronics home stereo speaker setup is wired in exactly the same way.)
**(Actually, what will probably happen is the amp will have a protection circuit that shuts it down before damage occurs, but that still means your amp isn't working.)
The original idea was for an adapter to be made so that I could use my Partadox with its SE plug with an adapter on my ALO MKIII-B to it's balanced out plug. My Paradox although it has a SE plug is currently being rewired with a mini xlr cable which is removable and can be interchanged with Audeze cables. I told LFF if he thought the adapter could be safely implemented with the Paradox to carry on. From what I've read the adapter would be a no go on my Q701 due to its cable wiring unless i had the Q701 hard wired differently from stock?
