The World's High End Monolithic Stereo Amplifier

Acuhorn RATE. I have the pleasure to present a truly audiophile solution to the modern amplifier design. The world's highest performing, high-power, monolithic class-D stereo amplifier chip by Texas Instruments. Working together with the power supply that is the latest development of the best Vicorpower. Analog input by Lundahl high impedance transformers and Welwyn Nichrome thin film resistors SMD are used for volume control. Eco-friendly, the best efficiency of the amplifier on the market. Here is the amplifier with performance better than ever before.

Monolithic class-d stereo amplifier chip by texas instruments. The integrated solution can offer a reduction in size. Reliability only a few components on the board. The audiophile selection of each component is a listening session.

Advanced PurePath Ultra-HD technology. Up to 90% efficient with 60 micro ohm MOSFETs. Audio bandwidth 100KHz. Total harmonic distortion + noise <0.005%. Output noise, A-weighted <60uV. Signal to noise ratio >111dB (A weighted). Dynamic range 115dB. Protection of both amplifier and speakers.

Stepped attenuators are the most preferred solution in high end audio. High quality precision 0.1% thin film Nichrome chip resistors. Subsonic bass, low bass and bass are the best with this type of resistors. Outstanding sound clarity, precise signal and soundstage.

Lundahl transformers is a world leading of high performance audio. The amplifier input is isolated high impedance input transformer. Specially selected for work with direct output from the R2R dac ladder. Extreme audio path high quality and transparent sounding.

Power supply is the best Vicorpower modules. DC-DC converters provide high power density and low noise high frequency Mhz switching. Advanced power processing in a small size. Autoranging 90-264Vac network voltage, for worldwide use.
