Purchased from an Audio Dealer, it was a Demo model with light use. This Aurilac ARK-MX+DAC has been well reviewed. Its fit ,finish & parts lineup is that of similar components costing 3 to 4 times the price...
ARK MX+ is a 32 bit/192KHz USB D/A converter which has been created for modern leisure lifestyle. It is advanced in design, powerful in functions and precise in musical representation.
Based on ActiveUSB™, AFN402™,Alire™, Purer-Power™, self-adapt upsampling circuit and other innovative patents solely owned by AURALiC, ARK MX+ could enable its user to fully enjoy the musical beauty by perfectly replaying the Hi-Rezformat music, and discovering every detail in original recordings.
In the mean time, AURALiC is operating under a very strict examining system. It not only pays special attention to the testing and selection of key components, but also focuses on the subjective evaluation of products. Every single product is to be listened and checked carefully by the designer...
The joint venture of a number of brilliant tech-audio trained individuals made the manufacturing of this impressive digital a reality...
The passionate research that went into this idea as to address all known pitfalls within the digital domain certainly is apparent upon having this magical Auralic Ark in one's system...
Right out of the box it's visually and physically evident the ARK MX+ was built to a very high standard. This 12 lbs. DAC made of iron, nickel, and silicon looks and feels like it was built to military specifications.
As the photos show, the component is in Mint as New Condition...
The AURALiC Sanctuary Audio Processor is jointly made by AURALiC and its technical partner Archwave AG in Switzerland. Sanctuary is based on the powerful multi-core ARM architecture, with the calculating capability as high as 1000MIPS. It could handle 32Bbit/192KHz multi-channel real-time audio stream...
Resorting to the ActiveUSB™ technology from AURALiC, ARK MX+ has overcome the transmission limitation from traditional Asynchronous USB which could only adjust +/- one clock cycle error of data package in isochronous clock. With mass data buffer technology and multi-stage, high resolution PLL circuit, ARK MX+ could buffer audio stream as long as 2 seconds, which could prevent time-based jitter resulted from the limitation of computer.
Self-adapted Upsampling Circuit...
Upsampling to higher sample rates make improvements to fine detail, sound stage depth and image separation. The self-adapted upsampling circuit inside ARK MX+ could automatically choose the best upsampling ratio. It could convert 44.1 KHz & 88.2KHz to 176.4KHz or 48KHZ & 96KHz to 192KHz. Such self-judgment uses proprietary interpolation technology to provide the highest possible fidelity at all sampling rates from 44.1KHz to 192KHz, so as to precisely restore the originality of music by avoiding the signal distortion from non-integer upsampling algorithm.
Low Noise DC Amplification Circuit
ARK MX+’s analog circuit adopts low noise DC amplification circuit designed by AURALiC. All the components have been manually examined and preciously matched. Low noise DC amplification circuit is the working fruit from the engineering team after long-term design and optimization. It is low in noise and distortion but wide in dynamic range. Moreover, since there is no couple capacitance in signal path, the purity of audio signal could be ensured; thus, the replay of music turns out to be naturally alive and silky smooth.
