The I22 is a two x 80 watt integrated amplifier utilising our acclaimed proprietary UFPD power technology. 

It is designed to provide high power output with very low distortion and system control.

An optional DAC board is available for the I22, comprising three digital inputs for the upgrading of existing CD players via their digital outputs, 

and the streaming of music files from PCs and Macs. There is an isochronous USB-B input (16-24bit data at 44.1 to 96kHz), 

a TOSLINK connector (16-24 bit data at 44.1-192kHz) and SPDIF (16-24bit/44.1-192kHz). 

Specialised processing at the Isochronous USB-B input re-clocks the incoming data for reduced jitter and greater bit resolution through the DAC, 

optimising sound quality from music files.
