It has been many years since the AKM DAC solutions were researchedby Yulong team, whose in-depth knowledge about the AK44xx gained through thejourney of countless prototypes, experiments and fine tuning, had contributedto the success of our very popular products such as the U200, ADA1 and thehighly acclaimed DA9.

As usual we did not stop; a DAC/Headamp/Preamp with highcost-performance ratio was in mind and rigorous R&D has been done to bringyou this brand new all-in-one desktop product Aquila.

All of its inputs namely USB, S/PDIF and Toslink all support DSDDoP128 and PCM384K formats. Small foot print, full featured IOs and functionscombined with superior technical and acoustical performance make it an excellentpart of your headphone or speaker Hi-Fi system.

Digital process is deployed with a SA8804, which supports DoP64, DoP128,PCM 24bit 384KHz through SPDIF and features ultra-low Jitter precision PLL clocking.

The de-jittered and precision clocked digital signal is then fedinto AK4497 with ultra low noise regulator for its analogue power supply andV_ref.

Ultra low distortion OPAMP OPA1611 and OPA1688 are used in the LPFstage, and followed by a high current low distortion OPA1688 output buffer. Thepreamp and headphone level is controlled by PGA2311.

The shielded, high quality custom made main transformer has aunique character of an isolator, which filters out high frequency noises fromthe mains power lines and guarantees performance under all power conditionsincluding heavy interference.

Outstanding S/N ratio and distortion performance evidences thesophisticated design and layout applications.

USB input is carefully implemented on XMOS U8 and it's built inswitching power supply is disabled and replaced by a dedicated linear low noisepower supply. A precise and low phase noise clock feeds the XMOS has its ownregulated power. DSD256 is supported via USB by customized Thyscon driver whichis well known for sound quality and stability.  

The headphone amp was carefully designed with TPA6120 for superiordriving capacity and natural sounding.

Unique sound modes are selectable to fit your taste of listening.Mode 1 is balanced; and mode 2 is delicate and firm which might be preferredfor classical music; mode 3 is laid back with stronger voice presence whichmight be beneficial to jazz vocal and similar. Working together with 3 filtermodes, you might find lots of interesting combinations to bring your favoritemusic to a brand new level of enjoyment.

DAART is well known for the effort in fine tuning the sound. Agroup of experienced users include audiophiles, electronic and acousticengineers and recording/mastering studio engineers spent their time inlistening and benchmarking in very different environment and equipment andcollaborate in he development, guarantees that Aquila not only measuresexceptional but also sounds stunning.

You will appreciate the craftsmanship and details such as seamlessaluminum housing, composite tiger claw suspension feet and fine knurled knob.
