HiFiMAN HM802u Digital Music Player
The Power of Good Sound
Relaxing, Mellow and Smooth
The HM802U inherits and expands on all the award-winning features from its predecessor high-end music player HM802 The digital design follows the footsteps of the flagship player, HM901S, and the sound quality pays a tribute to HIFMAN's legendary music player, the HM801.
The new CNC alloy casing combines sleekness and high durability. It prevents system crashes due to temperature issues and other disturbances. This results in largely improved system reliability.
Excellence at its Finest
1 The revolutionary OPA627 opamp functions at its highest capacity with the optimized circuit design to pursue the vivid imitation of hi-fi audio quality.
2. Each channel is equipped with one WM8740 DAC chip for its unique qualities. The result renders high-end and premium sound quality.
3. Using Line Out Output as the source when connected to the amplifier produces performance that rivals more expensive and bulkier desktop amplifiers.
4. Interchangeable amp cards, cables and compatibility with the HM901S dock pro-vides for maximum convenience.
5. Two pairs of dual-voltage solution without coupling capacitors helps eliminate noise from the power-supply to further improve the sound quality.
Advanced Step Potentiometer FOR VOLUME CONTROL
The patented step analog volume control is designed for precise control and accurate channel balance (with less than 0 001 in errors). The resistors in both channels of the step potentiometer are painstakingly paired to ensure that they are functionally identical. This results in excellent channel balance and soundstage.
Furthermore, in order to drive ear-phones of high sensitivity, HIFIMAN's Advanced Step Potentiometer has a better and smarter gradual attenuation design, particularly at low volumes. This helps avoid inconsistent volume levels and channel imbalance when increasing or decreasing the volume.
Modular Amplifier Cards
Personal audio comes with headphones with high, low impedance and sensitivity, over-ear, on-ear de-signs. This also includes highly sensitive in-ear moni-tors or earphones. As such, it is incredibly difficult to satisfy the various requirements of all these units with a single circuit.
The HM802U 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 HM802U offers true balanced output capability, increasing resistance to interference, widening the soundstage, and improving detail and separation.
The selection for amplifier cards includes an option for sensitive in-ear monitors, and a MINI-BOX and MINIBOX Gold card specifically designed for over-the-ear headphones. The balanced card is designed for headphones with a balanced termination, often indicated with a 4-pin XLR connector.
HM802U+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 head-phone or earphone. Once again, it defines the keynote of HIFIMAN products: relaxing, mellow and smooth. HIFIMAN takes this a step further by reducing the heat emission and gain higher indication. It is particularly adaptable for even the most difficult-to-drive headphones.
