Q: Would this be ok for 8ohm - 80w passive speakers?

No. This is a headphone amplifier with 160 *milliwatt* output. Unless you want to clamp one passive speaker to each side of your head, you won't hear much.

Q: Would this work with 250 ohm beyerdynamic headphones?

Yes, but it wont be as loud compared to something with more power to drive higher impedance headphones.

Q: is this an amp or a dac? and would it be a good pair for a senhieser HD560s?

This is a DAC with amp-like controls, and yes the HD560 impedance is 120 Ohms, this DAC can power up to 200.
