Why settle for less when you can experience the pinnacle of audio clarity with the Callia Reference Stereo USB DAC Designed and meticulously crafted in the United Kingdom, this high-quality, advanced digital-to-analog converter (DAC) is a testament to Prism Sound's unwavering commitment to superior audio quality.
The Callia DAC is not just a device, but a gateway to an immersive audio experience. It unveils the most subtle nuances of any performance, effortlessly adapting to a diverse range of music genres. This professional-grade DAC allows you to hear your music exactly as the creators intended, right in the comfort of your own home.
The Callia DAC's pristine sound quality is uncompromised, thanks to our rich heritage and unparalleled experience in the audio industry. This powerful device delivers unparalleled sonic clarity, transforming your listening experience into an auditory feast.
Equipped with a high-current, low impedance headphone output, the Callia DAC is optimized for peak performance. It's capable of powering a broad spectrum of high-end headphones, adjusting and matching the impedance to provide an unbeatable listening experience.
The Callia DAC's sophisticated design also includes simplified connectivity. Compatible with a wide range of computer hardware via a USB2 interface supporting UAC2 audio, it features auto input detection and output protection. This allows for the hot plugging of cables without the risk of damaging your speakers.
Prism Sound's extensive history in developing test and measurement equipment for the audio industry has endowed the Callia DAC with unsurpassed clocking and jitter rejection. This ensures the most accurate and detailed conversion available, making it a top choice for audio enthusiasts.
The Callia DAC supports linear PCM in 2's complement binary coding and, using the "DSD over PCM" (DOP) protocol, DSD at the original bit-rate (DSD64) and also at 2 x the original rate (DSD128). It's capable of playing DSD files encoded as "DOP" with both ASIO and WDM drivers.
On the S/P-DIF inputs, DOP can also be used, but only at the original DSD bit rate (DSD64) as these connections do not have enough bandwidth for DSD128. The ASIO native DSD format is not currently supported.
Compact yet powerful, the Callia Reference Stereo USB DAC is the perfect companion for those seeking a high-quality audio experience, whether at home or on the go. Experience the difference with Callia today.
