Audiozen Audio has unveiled the Audiozen P-Stone stereo power amplifier , which uses a class AB Si-C MOSFET output stage based on quasi-complementary symmetry silicon carbide. This solution is complemented by a Baksandal diode that eliminates the local Miller effect and provides excellent linearity at high frequencies.
Silicon carbide is characterized by the highest strength and the ability in MOSFET technology to provide an increase in switching speed – Si-C MOSFETs are three times faster than classical silicon MOSFETs, and the minimum input and output currents of elements based on silicon carbide are an order of magnitude lower than that of a conventional MOSFET . The high thermal conductivity of silicon carbide, which is approximately three times higher than that of silicon components, has reduced the requirements for the design of the cooling system.
The novelty is clothed in an all-aluminum case and is equipped with high-quality audiophile connectors. But the main innovation is located on the front of the amplifier. Here’s how the manufacturer describes it: “We are the first brand to equip power amplifiers with a pair of analog meters that use words instead of numbers. Pleasure level indicators are divided into many areas of pleasure, from the muted and meditative zen volume to the first watt of power in the hot sex zone to the central fun zone evoking memories of pure pleasure. listening, reaching with a further increase in the volume of the “concert” zone (gig) “ .
