HIFIMAN HM901S overview

  • 1Description

The HM901s High-Resolution Portable Music Player from HIFIMAN utilizes a pair of the ES9018 DAC high-performance chips from ESS Technology. Two chips per individual channel provide warm sound and remarkable midrange reproduction. The player supports Direct Stream Digital (DSD) 2.8 MHz files for high-quality playback and decodes 24-bit 192 kHz high definition music files, while also upsampling to 24/192.

The MINIBOX Gold Amp Card helps deliver high-fidelity live music, thanks to its metal can that offers temperature stability and resistance to electromagnetic interference. There are up to two OPA634U and BUF634U amp circuits that provide a wide frequency range and a higher SNR. Its circuit design without a coupling capacitor achieves the fidelity to reproduce realistic sound of music by reducing distortion.
