H2OAmp™ - H2OAmp™ (Hybrid High Output Amplifier) is specially engineered to meet the amplification need of NEAT™ driver unit. To drive NEAT™( a capacitive load), we need hundreds of output voltage and plenty of output current to extend frequency response. We achieve the goal by both active and passive gain stages and proprietary class-D (for portable) or class-AB (for home) architecture. In the near future, we are developing a D3Amp (Digital Direct Drive) to further improve its efficiency
