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 generationActiveUSB ™ to VEGA that separates the USB PHYinto 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 PCMsignal in 32bit) but also able to decode DSD stream at 2.8MHz (DSD64), 5.6MHz (DSD128) and 11.2MHz (DSD256) natively though 'DoPV1.1' transmission standard.
Flexible Filter Mode
The Flexible Filter Mode technology inside VEGA has six built-in modes each contains several digital filters optimized for corresponding sampling rate. These filters are developed under AURALiC's subjective auditory sense and objective testing data relationship models which is 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 nativeDSD conversion. To maximum usage of these filters, VEGA allows its user to customize according to different formats, tuning sound best to personal preference.

Femto Master Clock
The objective of Femto Master Clock technology is to give DAC and upsampling circuit an ultimate clock with extremely low jitter and low 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 at 82 femtoseconds. What's more important, the phase noise which affect sound quality a lot has been dramatically reduced to -168dBc/Hz. VEGA has three level of clock precision for customer to choose, with the highest grade 'EXACT' mode, it will give the purest reference clock. Driving by such amazing clock, VEGA can easily reproduce the music details in the 'last bit', represent a rock solid stereo image you may never experience before.
Using latest ground breaking algorithm, MegahertzUpsampling technology process and up-sampling all incoming PCM signal to about 1.5MHz in 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 brand 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.
AURALiC ORFEO Class-A Output Module
In order to drive various loads, matching different power amplifiers, VEGA is powered with AURALiC's patented ORFEO Class-A module which is inspired by Neve8078 analog console’s circuit design as the output stage. 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 for600ohm load without any distortion raise.
