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 .

Introduce
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 .
Even 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 . For 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

* 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.
