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.
