The i21 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.

Another key design feature is a digital volume control to ensure excellent channel balance and a flat frequency response at any volume, and 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.

Primare's characteristically rigorous embrace of superior electrical design and aesthetic rendering has forged a perfect union between the I30 and the other 30 Series models including the CD31 CD player. Here, performance compatibility is expressed by the creation of a balanced signal path between player and amplifier: a revelatory connection, which eliminates noise and preserves fidelity right through to the speakers.

The I30 is capable of delivering 100watts into an 8 ohm load and 180watts into a 4 ohm load. Its robust topology means that loudspeakers will always receive a highly stable and symmetrical signal.

The CDI10 is based on Primare's years of experience in designing digital and analogue playback systems.
The amplification is a class-D switch mode design capable of delivering 75 watts into an 8 ohms load.

From the high performance DSL 710 CD transport, used with excellent results in several more costly Primare units, through the PCM1738 D/A converter performing conversion from the CD-player and the DAB / FM receiver module, to the wide selection of inputs and outputs, only first class components have been used.

Special attention has been given to quick connection of MP3 players, minidisk recorders and headphones. A combined headphone and line input socket suitable for an MP3 player or minidisk connection has been incorporated at the front of the unit. Fully in line with the Primare "ease-of-use philosophy" the CDI10 is equipped with a graphic display and buttons for direct access of the most commonly used functions making this component a fine example of how to create a truly intuitive user interface.
