Will the XPA-2 Gen3 damage the Q750?

No. The XPA-2 Gen3 is rated for the Q750's 8 Ω load as it comes.

What impedance setting should I use for the Q750 on the XPA-2 Gen3?

None: the Q750 is 8 Ω, and the XPA-2 Gen3 needs no change for it.

Is the XPA-2 Gen3 powerful enough for the Q750?

More than you need. From a seat 2 m away, loud 95 dB movie peaks take about 21 W per speaker, and the XPA-2 Gen3 is rated 300 W per channel. Cinema reference level, 105 dB peaks, takes about 201 W.
