X-Series_Amp_Heat_Sink

Cast Aluminium Heat Sink 

The X-Series Amplifiers can perform at their peak power levels for a large period of time due to the chassis being a solid cast aluminium heat sink. The newly designed heat sink allows for hot air to rise out from the top, which causes a vacuum that draws in cool air from below. This provides thermal control for an uninterrupted listening experience.
