-Hi-End 56VA R Core universal transformer
-Universal transformer, work with 110~120Vor 220~240V AC.
-Super low noise, work best for DAC/Preamplifier,source type devices

-OutputSPDIF(Optical or Coaxial) or Analog L and R
-Input USB [This itemdon't have SPDIF(Optical or Coaxial) Input],
You can buy this iems: http://www.qlshifi.com/en/wzcapi/pcm1798_usb_dac.htm Ifyou need SPDIF Input.
-Analog Output can choose add tube bufferoutput or directly from I/V convertersOutput
-Such as double side gold coat PCB with highquality soldering.
-Power: Independent power supply byAMS1117-3.3,AMS1117-5,MC7808,LM337,LM317,KA7806

-Burr-BrownNE5532P*2 OpAmp I/V converters
-Burr-Brown OPA604AP*2 OpAmp LVP
-Power Supply0-8V(2A),0-60V(0.4A),15V-0-15V(0.4A),(Include)

The USB interface into the PCM2707,and then directly through I2S input toPCM1798.
The PCM1798 output uses 4 OP Amp to I/Vconverters and LVP. The USB DAC output youcould select directly from OpAmp or add tubebuffer.
The USB DAC also provides two-way digitalsignal output: optical SPDIF output andcoaxial SPDIF.
