HiFiMan Musical Amplifier Card for HM901 Audio Player

$199.99

The HiFiMan Musical Amp card is an upgrade for your HiFiMan HM901s, MH901U and HM802U Media Players.

The Musical Amp Card utilizes a fully discrete component design from the mainstream opamp and buffer design.

The Linear circuit and high bias voltage design allows you to experience music to the fullest extent.

Features:

  • Fully discrete Musical Amp card
  • Classic vacuum-tube tone
  • Great for genres such as Classical, Vocals, Jazz and Small Chamer Orchestra

 

Fully Discrete

The all-new Musical Amp Card is the first completely optimized and fully discrete component designed for a portable music player. 

The discrete amp card has the advantage of breaking free from the limits of an op-amp design to feature a better listening experience and higher-end performance.

The HiFiMan engineering team has finally achieved very fine tuning as a result from a long-term, wide-ranging and tedious trial and adjustment period. 

Musicality

The resulting Musical Amp Card reveals a mellow and silky vacuum-tube style. Not only does it provide a solid ground for Classical music, but it also renders Vocals, Jazz and Small Chamber Orchestra even more pleasant to your ears. 

The High bias voltage design reproduces near-perfect music via class A power amplifier. The Classic Vacuum-Tube tone is rich, natural and simple.

The tuning technique of the Musical Amp Card meets the requirement of the mainstream "High Resolution Music Player" with the high level reproduction details. You can enjoy smooth, seamless full-range music reproduction.

Circuit Design with Detials and Precision

Using several highly reliable Solid Tantalum Chip Capacitors along with numerous Onsemi small signal transistors to form the unique design, the Musical Amp Card features a classic differential amplifier as input and is supplemented with a NEC 2SD882 on both sides.

The whole circuit is rendered smooth with very low noise floor and higher gain.
