AURALiC VEGA DSD DAC
Includes Silver Mogwai S/PDIF and balanced XLR cables!
The next generation digital audio processor offering DXD & DSD, plus remote control. Developed with the goal of seeking non-compromised sound, with plenty of I/O ports and powerful functions, it will become the kernel component of your high-end stereo system.
With the Sanctuary Audio Processor as its heart, AURALiC introduces several cutting-edge technologies for VEGA: Megahertz upsampling algorithm up-samples all PCM music to 1.5MHz in 32bit; Femto Master Clock provides 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 a 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 analogue outputs can connect to a power amplifier directly, adjusting volume in digital precision without dynamic loss.
The six built-in filter modes each contain several digital filters optimized for corresponding sampling rate. These filters are solely developed by AURALiC to optimize the listening experience for different music and formats. VEGA allows its user to customize according to different music formats, tuning sound to personal preference.
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 the DAC, but also create a new Nyquist frequency for all PCM signals further away from the top end of audio frequency. As a result, AURALiCs engineers are able to design a bran-new analog circuit structure with more bandwidth and faster slew rate. Compared to previous designs, 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.
The purpose of the Femto master clock is to give the DAC and upsampling circuit 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 a 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. Driven by such an amazingly clean clock, VEGA can easily reproduce the music details to the 'last bit', represent a rock solid stereo image you may have never experienced before.
VEGA has six built-in filter modes, each containing 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 is also slow roll-off filter and several noise filters for native DSD conversion. To maximize usage of these filters, VEGA allows its user to customize according to different formats, tuning sound to your best personal preference.
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 Neve 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 characteristics. 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 whilst maintaining its driving capability for 600ohm load without any distortion raise.
