Forbidden City-Ping is mainly designed to introduce real hifi perfomance into 3-in-1 system! With all hifi grade components applied, it consist of a hifi CD-player, a FM/AM tuner and a 100w solid-state stereo amplifier, and more over, featured with a special made USB input port, which is very useful interface that the whole family can play all types of music through Ping, from CD discs to all music formats computer based.

- Linear technology applied in DAC stage
- 100 watt output power delivering per channel
- Cool Class A technology applied in amplifier stage
- High quality FM/AM tuner stage employed
- All functions remoteable

Linear technology (applied to DAC stage):

-Non-oversampling, no digital filter
-J-FET/Transisters filter, no op-amp at all
-Passive I/V conversion In progression
-Short pass length, minimal number of parts

Cool Class A technology (applied to Amplifier):

Combined the advantage of class AB and the class A technology, the Cool Class A technology actually achieved same linear sound performance essentially but without normal need of big electrical current, as Class A does.

SpAct memory architecture (applied to USB interface):

It's unique system that recovers the audio clock from USB.
Analog pulls with SpAct enable playback with very low clock jitter.
