When ordering POLARIS, you can add a 25-inch hard disk drive or solid state drive as internal music storage as an option, turning POLARIS into a full function music server. Since there is no capacity limitation, you can always purchase POLARIS and install the storage by yourself.
     
    Analog Channels & Phono Stage
    POLARIS is equipped with two pairs of multi-function RCA connectors - these two stereo pairs of analog channels can be configured as a phono stage input, a line stage input or pre-amplifier output through the product settings menu. Digital inputs include AES/EBU, Coaxial, Toslink and a USB connection to a computer working as a standalone USB DAC.
     
    AURALiC Tesla Platform
    POLARIS is powered by AURALiC's proprietary Tesla hardware platform that includes a Quad-Core Coretex-A9 processor running at 1GHz, 1GB DDR3 onboard memory and 4GB system storage. The Tesla platform has a calculation ability of 25,000 MIPS, more than enough to decode a vast spectrum of audio formats, including AAC, AIFF, ALAC, APE, DIFF, DSF, FLAC, MP3, OGG, WAV, WV and WMA. AURALiC has chosen this platform for its flexibility and long term support consideration. Future features planned include DSD Upsampling, Room Acoustic Treatment. All these features can be delivered through automatic online updates without users attention.
     
    Femto Master Clock
    The dual-frequency Femto Master Clock inside the POLARIS is specially designed and optimized for its ESS Sabre DAC chip: with one frequency for playing music with a sampling rate which is the multiple of 44.1K, and a second for 48K, making it possible for the POLARIS to be able to lock on with highest clock precision (equal to the VEGAs EXACT mode) at all time without dropouts. The Femto Master Clock, which is powered by a 9uV extremely low noise dedicated power supply, has a very low phase noise performance. It not only has dramatically low phase noise, which is only at -151dBc/Hz level, but also an excellent 100Hz offset noise level which is only -115dBc/Hz. Driven by such a high performance clock, the POLARIS can bring you vivid music with natural detail and a solid sound image.
     
    Hybrid Volume Control
    AURALiC is introducing another innovative technology: Hybrid Volume Control for POLARIS. The Hybrid Volume Control uses both analog and digital volume control together for optimum audio performance and the best possible sound quality. The analog attenuators reduce the signal level in 12dB steps whilst the DAC's internal digital volume control handles small amounts of volume change within each step. By using this technology, the DAC chip always operates in the best performance range, bringing much lower distortion, better dynamic range and high sound quality at low volume levels.
     
    Flexible Filter Mode
    POLARIS has four built-in filter modes which allows its user to customize sound best befitting their personal preference. Those filter modes were developed from AURALiCs well known Flexible Filter Mode in the VEGA Digital Audio Processor, with each containing several digital filters optimized for a corresponding sampling rate. Flexible Filter Mode was developed under AURALiC's subjective auditory sense and objective testing data relationship models, to optimize the listening experience for different music and format. The Precise mode exhibits perfect in-band ripple and out-band attenuation performance, while the Smooth mode is better for overall enjoyment as it has no 'pre-ringing' effect. The other two modes, named Dynamic and Balance are optimized for different music formats as well.
