Roksan Caspian 4G Power Amplifier

Power amplifier

Relative price

typical

Among the 25 power amplifiers in the catalogue, this one is 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

I/O: accepts both RCA and XLR.

Competition record

Assessed against 19 rivals across the sixty systems: 8 head-to-heads won, 52 lost.

Where it gives ground

The dimension the engine names as the weakest link, counted across every head-to-head it lost.

  • vocal presence ×21
  • quietness at rest ×19
  • timing and drive ×8
  • low-level clarity ×6
  • bass control ×4
  • midrange truth ×3
