The Auralic VEGA, the next generation digital audio processor, is developed with the goal of ‘seeking for non-compromised sound’. With plenty of I/O ports and powerful function, it will become the kernel component of your high-end stereo system.
With Sanctuary Audio Processor as heart, AURALiC introduces several cutting-edge technology for VEGA: Megahertz upsampling algorithm up-samples all PCM music to 1.5MHz in 32bit; Femto Master Clock provides an ultimate clock precision with jitter only 82 femtoseconds(0.082 picosecond). Binding with other AURALiC’s patented technologies such as ‘ORFEO Class-A module’ and discrete ‘Purer-Power™ solution’, VEGA will bring high resolution music playback experience to climax.
VEGA supports all high resolution music formats including DXD(352.8KS/s, 384KS/s in 32bit) as well as DSD stream at 2.8224MHz and 5.6448MHz. Five digital inputs include AES/EBU, coaxial(set of two), toslink and USB. The balanced and single-ended analog outputs can connect to power amplifier directly, adjusting volume in digital precision without dynamic loss.
The Flexible Filter Mode embedded inside VEGA has six modes, each contains several digital filters optimized for corresponding sampling rate. These filters are solely developed by AURALiC to optimize the listening experience for different music and format. VEGA allows its user to customize according to different music formats, tuning sound best to personal preference.
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 DXDformat(352.8KS/s and 384KS/s PCM signal in 32bit) but also able to decode DSD stream at 2.8224MHzand 5.6448MHz in native though ‘DoP V1.1’ 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 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. Please download the technical white paperof Flexible Filter Mode for detailed information.
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.
Megahertz Upsampling:
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’spatented ORFEO Class-A module which is inspired byNeve 8078 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 ORFEOmodule used in VEGA has been selected and tweaked for lower noise while maintains its driving capability for600ohm load without any distortion raise.
