The RCA coaxial output of the standard DI-2014 can't compatible with Master 7 but can compatible with other devices. For the Master 7, the best connect is through I2S or BNC .

Audio-gd products had design and test based on the AP SYS-2722 (The top-drawer professional equipment in world)

What is improve than the DI-V3?

       The DI-2014 had built in same USB chip with our current  DACs . The most different is had much better power supplies than the DAC built in chips.
1,    The DI-V3 had got a lot user's good feedbacks ,  it had built in 3 groups PSUs but had not built in power supply , so limit by the user's external power supply (USB power or universal power  )  can't get the best performance .  E
ven though user applied the audio-gd power supply, the DC transmit cable  still have the serious effect on sound quality .
       The DI-2014 had built in ultra high performance power supplied, include 5 groups class A PSUs , the class A PSUs had  ultra high input impedance and low output impedance can block the disturb through power supplies effect the sound quality.
2,    The DI-V3 had one group PSU supply for the USB-32 chip and the SPDIF input controller chip .
       The DI-2014 had applied 3 groups PSUs supply the USB-32 DSD chip , separate power supply for the core , I/O , PLL and clock .  These processes made the performance and sound quality had much improved  . Especial the clock and PLL power supplies,  applied the negative-feedback power supply ( PSU chips or some Linear PSUs)  or power supply common with other circuits  will make the phase noise increase to large level and much degrade on sound quality .  Our all class A PSUs  are non-feedback design .
       In the DI-2014, the SPDIF input controller chip had separate class A power supply . The Power supply is the source of anythings in audio world!
3,    The DI-V3 had the USB power supply option so the USB cable had connect the +5V line from computer which is degrade on sound quality .
      The DI-2014 had not connect the +5V line for less interrupt from computer.
4,    Ultra short signal journey design,  all the signal through only one stage high speed and strong drive ability  logic chips  , can avoid signal delay and the digital wave smooth off .
What is improve than the USB parts built in the DACs?
      The DI-2014 had built in same USB chip with our current  DACs . The most different is had much better power supplies in the DI-2014 . F
or all, the DI-2014 sound quality still effect by the output coaxial cable, I2S cable and power cable , these must  the users take care of them.

Summarize
Built in 5 Groups Fully Discrete Class A power supplies  .
Built in ultra high performance power supply , don't need external power supply
Applies Current Conveyor Technology for coaxial output ( Output 2)

Coaxial input support 16 / 24-Bit A 44.1kHz, 48kHz, 88.2kHz, 96kHz,  192kHz
Optical input support 16 / 24-Bit A 44.1kHz, 48kHz, 88.2kHz, 96kHz
USB conversion to I2S output support 16 / 24 / 32-Bit A 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz , 352kHz , 384kHz
Support DSD64 / 128 from I2S output
Two model coaxial outputs * :
             BNC (Applied Current Conveyor Technology,
support up to 16 / 24-Bit A 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz)*
             RCA (
Transformer  Transmit insulate ,support up to 16 / 24-Bit A 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz with most DACs except the Master 7 support up to 96K)


*     The Current conveyor output can cooperate with most standard
design DACs in world but some DACs can't cooperate . The transmit insulate model output can cooperate with all standard design DACs.
