Description

Hidizs has developed the DH80S to provide high-resolution sound playback. The device features excellent components, with an enhanced signal decoding chip ESS9281C, which has a high dynamic range, low power consumption, ultra-low distortion, and more. The collaboration of the DAC with two independent OPAMP amplifiers RT6863C allows the device to have an output power of up to 4 Vrms on the balanced output (4.4 mm).

Features:

  • Native DSD64/128;
  • MQA audio technology support;
  • ESS9281C PRO DAC chip + two RT6863C operational amplifiers;
  • 3-level gain selection and high output power;
  • Enhanced configuration to improve sound quality;
  • Magnetic adsorption design;
  • Support for Apple Lossless.

ESS9281C Pro chip + two RT6863C operational amplifiers

The device is powered by a high-quality DAC with the latest generation ES9281C Pro chip from Sabre Technologies, working in conjunction with two independent operational amplifiers RT6863C, allowing the device to have an output power of up to 4 Vrms on the balanced (4.4 mm) output. Moreover, the manufacturer says that the device has a very high-quality component base, including capacitors from Panasonic, Dual Crystal Oscillators, etc. The quality component base and well-developed software allow the Hidizs DH80S to decode high-resolution audio signals with full, 8x MQA decoding. Certainly, besides MQA, there is support for decoding PCM up to 32 bit / 384 kHz and DSD up to DSD128.

Sampling frequency indicator light

The LED indicator lights up in different colors: red: 44.1k-48k; blue: 88.2k-384k; pink: MQA. Synchronized with the sampling frequency being played at the moment.

Magnetic design

Thanks to the high-quality magnet, DH80S and AP80/AP80 Pro can be easily connected and securely fixed. The connection ports are also well protected.

Package includes:

  • DAC;
  • USB-C charging cable;
  • USB-C to USB-C cable;
  • Documentation.

Power output

This is the useful power developed by the amplifier in the load resistance. Amplifiers are usually characterized by the highest power that can be obtained at the output, provided that the distortion does not exceed the specified permissible value. This power is called the output power of the amplifier.
