I'm not sure what the output power actually is on the KA3 single ended socket but, I would expect your dt770 to be a stretch for it depending on your preferred volume. I used a Fiio BTR5 for a while with an IEM that has unusually low sensitivity, for an IEM, it was loud enough for me at 50% volume from the SE socket. This IEM's impedance was only 14 ohm, your headphone will be quite a bit more demanding. You could get an amp and feed it from the KA3, this is likely to be cheaper than buying a new DAC/amp.

Have you paired the 250 ohm DTT70 with the btr5? I'd imagine it won't be enough so I might as well get the 80 ohm one

I don't have the dt770, they should be a lot more demanding than the IEM I compared them to judging by the sensitivity and impedance.
