The amp sounds at its best with Pure Audio mode engaged – this turns off the display and any video circuitry that isn't being used.
As with some of the Onkyo's peers, we also found that dialogue in particular benefited from turning the amp's Audyssey EQ system off.
With it set to on, dialogue through the centre channel sounds a little unclear and lacks articulation. Turning it off brings the centre-channel action more to the fore and gives greater balance to the front three channels.
Muscular soundAs we've come to expect from Onkyo, the '607 serves up a muscular sound all round. During the echo game in House of Flying Daggers, it almost boils over with dramatic bass.
As Mei flings her scarf from drum to drum, each collision sounds earth-shattering. The surround field is open and detailed.
There's no questioning the explosive delivery, but we'd sacrifice a bit of this bravado for greater refinement and control.
Subtleties of soundtracks are sometimes lost among all that crashing and banging. And that's where the top all-rounders in this genre have the edge.
