I think the buzz or distortion comes from pairing a low impedance headphone with an amp that has a high output impedance. Always remember the golden rule:
The output impedance of the amp should (at least) be 1/8 of your headphones damping factor.
I personally wouldn’t hook up a dynamic driver headphone at around 20 ohm to anything with more than a 2 ohm output.
Also another thing to remember is that amps that come with both SE and balanced options often have twice as high an output impedance via the balanced jack.
