    The AK500A and AK500P may be small compared to typical amplifiers, but they deliver powerful performance through the strategic selection of components and perfect design.

    The principal goal of the AK500 Series is not to merely recreate the information contained in an album, but rather to transport the listener into the realm of emotion and intent sought after by the artist. Audiophiles can now experience unparalleled audio closest to the original sound through the AK500 series.

    Power Amplifier
    Approximately 3,000 times faster refresh rate was achieved by implementing a very high-frequency Switching-Mode Power Supply (SMPS) used in aerospace applications rather than a commonly-used linear power supply design, ensuring a full response to even the most complex waveforms. Despite its very small size, the power supply provides a full 1,000W of capacity.

    In addition, a full balanced design was used to minimize noise interference, and Power Factor Correction (PFC) was used to completely eliminate surge noise.
    Optical protection sensors are employed for the audio amplifier unit and protection circuits, which completely eliminate physical and electrical contact for maximum sound quality.

    Since capacitors typically found in amplifiers can introduce sound-coloring, a DC feedback loop design was implemented, and no capacitors were used.
    Furthermore, the input buffer, driver, and output stage were completely isolated from the audio amplifier unit in an independent design to eliminate cross-interference. The outstanding structure uses separate constant-voltage circuits to eradicate any deterioration in sound quality.

    Power Supply

    The exceptional speed, power, and control capabilities of the AK500AP are no match for any other comparable power amplifier.

    All of these features were carefully selected and implemented to ensure the most accurate interpretation and playback of complex audio data transmitted from the AK500N.
