In Stock, Available Now


Product Description

Cool Class A design,100watt solid-state amplifier, Ping is designed to introduce real Hi-Fi performance in a 4-in-1 system. With all Hi-Fi grade components applied, it consists of a CD-player, a FM/AM tuner and a 100w Cool Class A solid-state stereo amplifier, and USB DAC. 

- 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  
- 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.
