Mission 778X
Integrated amplifier
Relative price
well below typical
Among the 59 integrated amplifiers in the catalogue, this one is well below typical.
A band places a component against its peers and carries no price. It is deliberately the only price indicator on this page: a second one, measured against a different set, would narrow the two together far enough to give the figure away.
What it is
Mission 778X — IAG budget integrated with phono.
CORRECTIONS: catalog had power=35W (correct = 45W); pre_out=False (correct = True; PRE Out RCA documented in Mission official spec).
Half-width form factor (236mm wide, narrower than full IAG width). Compact desktop-friendly. Same ES9018K2M DAC as Leak Stereo 130.
Competition record
Assessed against 19 rivals across the sixty systems: 1 head-to-head won, 59 lost.
Where it gives ground
