Will the AVR-S770H damage the DB53?

No. The AVR-S770H is rated for the DB53's 6 Ω load as it comes.

What impedance setting should I use for the DB53 on the AVR-S770H?

None: the DB53 is 6 Ω, and the AVR-S770H needs no change for it.

Is the AVR-S770H powerful enough for the DB53?

Comfortable. From a seat 2 m away, loud 95 dB movie peaks take about 29 W per speaker, and the AVR-S770H is rated 75 W per channel. Cinema reference level, 105 dB peaks, takes about 284 W.
