Product Detail:
 
  Aquila. All of its inputs namely USB, S/PDIF and Toslink all support DSD DoP128 and PCM384K formats. Small foot print, full featured IOs and functions combined with superior technical and acoustical performance make it an excellent part 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 fed into AK4497 with ultra low noise regulator for its analogue power supply and V_ref.
 
  Ultra low distortion OPAMP OPA1611 and OPA1688 are used in the LPF stage, and followed by a high current low distortion OPA1688 output buffer. The preamp and headphone level is controlled by PGA2311.
 
  The shielded, high quality custom made main transformer has a unique character of an isolator, which filters out high frequency noises from the mains power lines and guarantees performance under all power conditions including heavy interference.
 
  Outstanding S/N ratio and distortion performance evidences the sophisticated design and layout applications.
 
  USB input is carefully implemented on XMOS U8 and it\'s built in switching power supply is disabled and replaced by a dedicated linear low noise power supply. A precise and low phase noise clock feeds the XMOS has its own regulated power. DSD256 is supported via USB by customized Thyscon driver which is well known for sound quality and stability.  
 
  The headphone amp was carefully designed with TPA6120 for superior driving 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 preferred for classical music; mode 3 is laid back with stronger voice presence which might be beneficial to jazz vocal and similar. Working together with 3 filter modes, you might find lots of interesting combinations to bring your favorite music to a brand new level of enjoyment.
 
  DAART is well known for the effort in fine tuning the sound. A group of experienced users include audiophiles, electronic and acoustic engineers and recording/mastering studio engineers spent their time in listening and benchmarking in very different environment and equipment and collaborate in he development, guarantees that Aquila not only measures exceptional but also sounds stunning.
 
  You will appreciate the craftsmanship and details such as seamless aluminum housing, composite tiger claw suspension feet and fine knurled knob.
