    HM802s - Potentiometer for Volume Control

    Carbon film resistors lack accuracy. Each channel can reach 5-10% in error production. This results in unbalanced soundstage and audible distortion.

    Digital volume control chips with no digital high frequency noise abatement can result in poor sound quality.

    The patented step analog volume control is designed for precise control and accurate channel balance. It is assembled with multi resistors network to improve attentuation accuracy to 0.001% bandwidth to 10mHz. Hifiman's Advanced Step Potentiometer is simply the best choice available in the current market.

    Modular Amplifier Cards

    Personal audio comes with headphones with high, low impedance and sensitivity, over-ear, on-ear designs. This also includes high sensitive in-ear monitors or earphones. As such, it is incredibly difficult to satisfy the various requirements of all these units with a single circuit.

    The HM802s features a user-replaceable slot for amplifier cards. As a result, it is now possible to use different cards to best fit the specific requirements of each headphone/earphone. The HM802s offers true balanced output capability, increasing resistance to interference, widening the soundstage, and improving detail and separation.

    HM802s + Power II Amp Card - The Powerful Drive

    The Power II Amp Card is upgraded from the one formerly used with the HM801. It features a simple yet elegant and pure circuit design to reduce noise, improve sound quality and increase usability with any headphone or earphone. Once again, it defines the keynote of Hifiman products: relaxing, mellow and smooth. Hifiman takes this step further by reducing the heat emission and gain higher indication. It is particularly adaptable for even the most difficult-to-drive headphones.
