CALLIA USB DAC and pre-amplifier

Designed and manufactured exclusively in the United Kingdom, the Prism Sound CALLIA USB Digital to Analogue Converter (DAC) and digital audio preamplifier is tailored for listening to music.

CALLIA is simply the best way to experience digital music. Coupled with high quality analogue power amplification and loudspeakers, CALLIA will deliver your music exactly as the recording producer intended. Whether it is early music, symphonic, choral, easy listening, elevator music, jazz, pop, hip-hop, EDM, garage, hard rock or something else, the clarity and neutrality of CALLIA will amaze you with its flexibility in the face of such different genres.

Using the acclaimed Prism Sound signal path, clock circuitry, ARM Cortex processor & USB platform of the Prism Sound professional range, CALLIA supports USB and S/P-DIF players.

No-compromise, full Prism Sound audio quality

The design goal for CALLIA was to provide Prism Sound audio quality in a sophisticated but easy to use package for listening to music at home. CALLIA makes no compromises on audio quality. CALLIA delivers the standard of audio performance demanded by top recording professionals at sampling rates from 44.1kHz to 384kHz**** or in DSD64 or DSD128.

CALLIA has the same no-compromise analogue circuitry as its professional cousins, with the same fully-balanced-throughout architecture and the same isolation barriers protecting the analogue from digital and computer interference.
