AURALiC Sanctuary Audio Processor
Sanctuary audio processor, the heart of VEGA, is based on multi-core ARM9 architecture with calculating capability at 1000MIPS which is ideal for handling multi-channel high resolution music. AURALiC also introduces the second generation ActiveUSB ™ to VEGA that separates the USB PHY into a discrete chip to future reduce EMI from computer. Resorting to these technologies, VEGA not only support DXD format(352.8KS/s and 384KS/s PCM signal in 32bit) but also able to decode DSD stream at 2.8224MHz and 5.6448MHz in native though 'DoP V1.1' transmission standard.
By using the latest ground breaking algorithm, megahertz upsampling technology can process and up-sample all incoming PCM format to 1.5MHz at 32bit depth. These not only improve the precision of DAC, but also create a new Nyquist frequency for all PCM signal which farther away from the top end of audio frequency. As a result, our engineers are able to design a bran-new analog circuit structure with more bandwidth and faster slew rate. Comparing to previous design, the new structure is more transparent to audio signal with lower distortion and less noise, it also lets red book CDs sound more rich and smooth.
Femto Master Clock
The purpose of Femto master clock is to give DAC an ultimate clock with extremely low jitter and phase noise. It utilizes aerospace grade crystal oscillator, ultra low noise linear power supply and temperature compensation technology to generate master clock with extremely low jitter performance at 82 femtoseconds(0.082 picoseconds). What's more important, the phase noise which affect sound quality a lot has been dramatically reduced to -168dBc/Hz. Driving by such amazing clean clock, VEGA can easily reproduce the music details in the 'last bit', represent a rock solid stereo image you may never experience before.
Fully Customized Digital Filters
VEGA has six built-in digital filters which are developed under AURALiC's subjective auditory sense and objective testing data relationship models. These filters are specially designed to optimize the listening experience for different music and format. The linear phase filter exhibits perfect in-band ripple and out-band attenuation performance while the minimum phase filter is better for enjoyment as it has no 'pre-ringing' effect. There are also slow roll-off filter and several noise filters for native DSD conversion. To maximum usage of these filters, VEGA allows its user to customize according to different formats, tuning sound best to personal preference.
AURALiC ORFEO Class-A Output Module
In order to drive various loads, matching different power amplifiers, VEGsA is equipped with AURALiC's patented ORFEO Class-A module as the output stage which inspired by Neve 8078 analog console’s circuit design. The principle of this module is to use a mass of small signal components with best linear characteristic. By packing them though a thermal balance procedure and bias the transistors into Class-A, ORFEO achieves impressive performance with open loop distortion less than 0.001%. The ORFEO module used in VEGA has been selected and tweaked for lower noise while maintains its driving capability for 600ohm load without distortion raise.
