As a team that has been practicing our expertise in high fidelity audio monitoring device design and manufacturing for the past 18 years, and one that has been pursuing excellence in revamping our knowledge of musicology and emotions that music itself delivers as a form of artistic expression, we firmly believe that a remarkable HiFi audio system should deliver a smooth, natural and translucent sound which can afford you a pleasant listening session that may last as long as you desire. It is part of the reason that we made many attempts over most of the time that we have existed to improve our products in order to achieve the ultimate purpose that we believe to be the faithful reproduction of the frequencies recorded by the artists and sound engineers.
We have concluded, that with such experience combined with our knowledge of advanced digital signal processing technologies, topped with extensive benchmarking and fine tuning of the reproduction of sound in different referencing audio system configurations, it is prudent for us to present you the Aquila III, our breakthrough product that will bring you an exceptional and blissful experience listening to your favorite musics.
The Aquila III features the 5th generation of Jitter and Interface Control (JIC) System in which an ARM microprocessor is added on top of the FPGA circuitry, an improvement from previous JIC system. By combining these two architectures, using our proprietary USB interface and the integration of the exceptional AK4499EX+AK4191 chips, it enabled us the addition of a true hardware decoding of the finest Hi-Fi digital audio format such as PCM1536KHz and DSD1024 to the Aquila III.
We are conscious of the opulent capability of the Aquila III that is almost excessive for most mainstream Hi-Fi audio formats. However, by building a superior machine, a stable operation, rich in bandwidth and processing speed with very low latency is made possible when paired with computers and mobile digital playback devices; therefore elevating the quality of your experience to a higher level altogether.
Powered by our proprietary FPGA platform, digital signal from either input is demodulated into bit-stream and then de-jittered by a FIFO buffer, synchronized to the low-noise master clock and engaged to a PLL. Then, an ultra-low jittered I2S signal stream is fed to the AK4499EX+AK4191 chipset for decoding referencing to the two ultra-low-noise 1.7nV power regulators. The decoded signal then passes through a carefully designed analog audio path that features a high current driven line and headphone amplifier output.
Although the parameter of bench top measurement is an important factor in our approach in designing our products, we feel that sufficing the individual perception of sound should be an unalienable property of any exceptional audio devices. We consider the principles of designing such devices based on purely measurement of performance lackluster. On the contrary, we have made decisions to refrain ourselves from pursuing outlandish numbers, but instead to direct our attention to obtain a balance between the two. Consequently, this choice dictated that our device will not produce record-shattering numbers, but it is a compromise we are willing to settle for in exchange of the resounding warm yet fervent signature tone that our machine is capable of producing. Our FPGA process features two clock modes. CLOCK1 is processed by the YULONG JIC: the DAC is operated at a lower oversampling rate to deliver a punchy, more round bodied analog sound. CLOCK2 is operated with the regular AK4499 sampling mode with outstanding resolution and details.
A highly anticipated Spectrum Analyzer function is now available thanks to the newly featured ARM processor. The analyzer or the whole display can be switched on or off by the user with ease.
Digitally controlled 99-step analogue volume control, fully balanced DC-coupled high current headphone amplifier that can drive headphones with 16Ohm impedance with great control and low distortion.
