I21
|
|
The I21 has an engineering heritage that may be traced through generations of class-beating ‘budget’ Primare amplifiers, each the beneficiary of an improved version of the ‘classic’ configuration of JFET input and bi-polar output devices, typical of far more expensive equipment.
The amplifier incorporates a massive 800VA toroidal transformer with separate windings for left and right power amp channels, effectively providing each channel with its own mono amplifier. The sheer physical size of this transformer makes it an inherently good mains filter and its low output impedance promotes good voltage stabilisation.
Another key design feature is a digital volume control to ensure excellent channel balance and a flat frequency response at any volume.
As many as four sources can use the I21’s muscular 75 watts and there are flexible output options including pre-outputs for an additional power amplifier.
