The different between dual ES9038 Pro and single ES9038 Pro is large:
                The different not only the DNR, but the dual ES9038 Pro working under mono mode, the channel crossing is improved for offer a larger and exact sound stage.

            Even the ESS9028 Pro, working under mono mode, its DNR had 3DB better than one ES9038 Pro .

The FPGA is important in the D-77:
           
1, Separate the data feed to dual ES9038 Pro for working in mono mode.
           2, Clock re-clock process and FIFO design for all inputs , the output data can exact synchronisation with clock signal, reject jitter.
           3, Built in high performance SPDIF interface , bypassing  low performance SPDIF interface of the ES9038 Pro .
What is  the FPGA duty  in the D-77:

           
1, Separate the data feed to dual ES9038 Pro for working in mono mode.
           2, Clock re-clock process and FIFO design for all inputs , the output data can exact synchronisation with clock signal, reject jitter.
           3, Built in high performance SPDIF interface , bypassing  low performance SPDIF interface of the ES9038 Pro .

Full discrete output stages:

          
 The signal last stage is  the analog output stags , they greatly  effect the whole DAC sound quality.
           The output stages working after ES9038 pro, they are full discrete transistor built with hole parts but not SMD parts .
           The high speed ACSS amps work as the signal gain and processing , they are of non feedback design and working in  current signal mode  . the dual ES9038 pro output [current signal] goes through the ACSS amp .
           In our design  output stages  working in pure class A , and without any negative feedback for the most pure and life like  sound reproduction .
           There are 4 pcs OPA built in as DC servo , so the DAC can be  working well without coupling caps  and output the most neutral sound.

Heavy power supplies design:
           There are in total 16 groups PSUs . 
           A total 13 groups of ultra speed linear PSUs  (dual stages PSU to  remove the power interruptions ). PSUs deliver cleanest power  to allow  digital circuits working under best conditions .
           2 groups of pure class A PSUs to  power  to the analog circuits and deliver most  analog sound .
           The control and display circuits are powered by a separate PSU  to  avoid adding any additional noise to the rest of the circuit.
