Ping is mainly designed to introduce real hifi perfomance in a 4-in-1 system! With all hifi grade components applied, it consists of a hifi CD-player, a FM/AM tuner and a 100w Cool Class A solid-state stereo amplifier, and more over, featured with a special made USB input port, which is a very useful modern interface that the whole family can appreciate all types of music through, from CD discs to all music formats that are computer based. 
                            - Linear technology applied in DAC stage 
  - 100 watt per channel power delivery 
  - Cool Class A technology applied in amplifier stage 
  - High quality FM/AM tuner stage employed 
  - All functions can be controlled via remote 
                            Linear technology (applied to DAC stage): 
                             -Non-oversampling, no digital filter 
-J-FET/Transisters filter, no op-amp 
-Passive I/V conversion In progression 
-Short pass length, minimal number of parts
                            Cool Class A technology (applied to Amplifier):
                            Combines the advantage of class AB and the class A technology, the Cool Class A technology actually achieves the same linear sound performance but without the normal need of a big electrical current, as in Class A.
                            SpAct memory architecture (applied to USB interface):
                            Its unique system recovers the audio clock from the USB. 
  Analog pulls with SpAct enable playback with very low clock jitter.
