Product Description

Highlight

  1. Dual AK4497 class A full balance amp,native full balance.
  2. Decoder and amplifier all-in-one ,well proportioned,double power supply design.
  3. Clock management ,2nd PLL digital plastic,DOP demodulation/modem,PCM/DSD depop switch and other exclusive technology.
  4. All interfaces support DSD decoding,digital broadcasting,USB supports 384K DSD256.

Technical features

  • The latest hi-end AKM AK4497EQ decoding chips, make no interference in L/R channels and purer sound
  • Clock management ,2 nd PLL digital plastic,DOP demodulation/modem,PCM/DSD depop switch and other exclusive technology.
  • Using full discrete component large current hi-end full-balanced amplifier,each channel uses two separated amplifier unit to form asymmetric output circuits.
  • Native full balance architecture, there is no any transition from DA to amp circuits,it is a complete four-way output volume.
  • Using two customized 50w audio specialized ring transformers to supply power separately to the amp and decoder,so that their power supply has no interference to each other.
  • Using own-created individual analog LPF cirtuits,the parameters of each level has been carefully adjusted to achieve the best conditions.
  • The all interfaces support DSD decoding :IIS supports DSD64,DSD128,DSD256,DSD512 decoding; SPDIF,Optical,AES/EBU support DSD64 decoding(DOP mode); USB supports SD64,DSD128,DSD256 decoding.
  • Rich digital filtering,two kinds of DSD: Wide BW/Narrow BW;six kinds of PCM: Short Delay Shar p / Short Delay Slow / Shar p / Slow / Low-dispersion Short Delay Filter/ Super Slow.
  • Adjustable screen brightness:it will return to the default brightness after 30s’no-operation;it will automatically remember the current brightness,and the next time you start up, it will keep the last setting.
  • The USB uses the USBAUDIO specialized U8 chip from XMOS,it can support PCM384, DSD256.
  • Full aluminum alloy box,two colors(silver and black) are available.
