Description

Hidizs has developed the DH80S for high-resolution sound file playback. The device boasts an excellent component base with an improved signal decoding chip ESS9281C, which has a high dynamic range, low power consumption, ultra-low distortion, etc. The collaboration of the DAC with two independent OPAMP RT6863C amplifiers allows the device to have an output power of up to 4 Vrms on the balanced output (4.4 mm).

Features:

  • Native DSD64/128 support
  • 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
  • Apple Lossless support

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, paired with two independent operational amplifiers RT6863C, enabling the device to have an output power of up to 4 Vrms on the balanced (4.4 mm) output. Furthermore, the manufacturer states that the device features a high-quality component base, including capacitors from Panasonic, Dual Crystal Oscillators, and more. The quality component base and refined software allow the Hidizs DH80S to decode high-resolution audio signals with full, 8x MQA decoding. Additionally, besides MQA, it supports PCM decoding up to 32 bit / 384 kHz and DSD up to DSD128.

Sample Rate Indicator Light

The LED indicator lights up in different colors: red for 44.1k-48k, blue for 88.2k-384k, and pink for MQA. It synchronizes with the sampling rate of the currently playing track.

Magnetic Design

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

Package Includes:

  • DAC
  • USB-C charging cable
  • USB-C to USB-C cable

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.
