Topping D70s MQA

Topping D70s MQA

  • 2*AK4497:AK4497 is flagship model in AKM company. We use a full AK4497 forevery channel in D70s.Resulting in better channel separation and batter spec. THD+N has even exceeded the performance marked by the AK4497 datasheet
  • DAC filter mode:D70s capable of providing 6 filter modes under PCM decoding, 2 filtermodes under DSD decoding, which, slightly adjust the details.(Note: it is not the same as EQ function.)
  • Support DSD512 & PCM32bit768kHz High Resolution Music:D70s uses 2nd generation 16 core XMOS XU216, USB supports up to PCM32bit768kHz, DSD512 native and MQA decode. With the help of customized Thesycon driver(for Win 7 or above), your PC will have better performance on ASIO playback.(Mac needn't a driver)
  • D70s has full balanced XLR output and single ended RCA output.You can choose "XLR only", “RCA only" or“XLR+RCA”output to meet different usage in the multiple systems.
  • Various input interfaces:D70s has various inputs: AES, USB, Bluetooth, Optical, Coaxial, IIS.Both USB and IIS support up to 21bit768kHz & DSD512 native. AES,Optical, Coaxial support up to 24bit192kHz. Bluetooth support 24bit96kHz LDAC transmission.
