Master series (Fully non-feedback design  ):

           The Master series apply the best design and technology of Audio-gd, they will become the Premier products of Audio-gd.
           They are true balanced designs applying the newest ACSS design which can improve the XLR connection to sound as good as the ACSS connection.
           They seem complex  , but in fact they are the most simple design the world has ever had , their a lot components to process the power supply. The Master-2 power amp only has a single "voltage " gain stage to process signals, working in ACSS mode so it is a current gain stage instead of voltage gain stage, whereas a normal OPA chip already includes two or three voltage gain stages. The simplest and shortest signal journey brings out the most neutral and least colored sound.
           From DAC-->Preamp-->Power amp, it is possible to have no feedback which can offer the best neutral sound. Although they are class A design, they do not have the same heat and power consumption as classic class A amps.
          They don't have the best specification on design papers but they are the best for listening. We have spent more than 6 months to design, listen and adjust. Their sound is extremely revealing, just like a wire with gain, so their sound won't be good all the time, depending only on how good or how bad the recording or source is.
          Please make sure you like the non-coloration sound before ordering to avoid wasting on gear that do not suit your tastes.
          The most skilled of Audio-gd staff build and test the Master series, and will test and burn in 300 hours before shipment.
