Rega io
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
NO PRE-OUT — entry-tier limitation. Cannot participate in AmpSet. ALSO no DAC + no digital inputs. Pure analogue minimalist integrated.
DEPTH 290mm: easily fits 305mm constrained cavity (well under 270mm practical limit). Smallest full-functionality integrated in catalog.
Competition record
Assessed against 17 rivals across the sixty systems: it takes the slot in none of its 49 head-to-heads.
Where it gives ground
The dimension the engine names as the weakest link, counted across every head-to-head it lost.
- low-level clarity ×8
- tonal body ×4
- bass control ×1
