QLS QA860 AD1955 24bit 192Khz DSD Lossless Digital HiFi Music Player


QA860 HiFi lossless digital music player (hereinafter referred to as QA860) is a set of digital player, DAC, headphone amplifier in one of the high cost HiFi equipment Internal power handling complex, real-time software architecture strongest, ultra-low Jitter clock and digital processing circuits, the unique strict isolation between circuits inside the machine design to ensure that it has a HI-END-level output characteristics.

The most conducive to sound software architecture
QA860 firmware continuation in QA660, still uses the QLS-HiFi exclusive patented technology --- microcontroller single-threaded pure tone player, unique procedural framework enables digital output with very low clock jitter (Jitter), and the digital audio output into the HI -END peak.

Support for mastering grade high bitrate file playback
QA860 can play 24Bit / 192KHz high rate of WAV digital audio stream, we know that the traditional CD-ROM only 16Bit / 44.1Khz, 24Bit / 192KHz digital mastering of data than conventional CD 5-8 times the amount of data (a 24Bit / 192Khz mastering songs almost the entire capacity of a CD), so the digital mastering both in the sound field, density, dynamic and resolving power so far beyond the traditional CD quality.

Digital DSD player that supports DSD direct play, direct decoding
QA860 can support DIFF and DSF files (DSD64, 1bit, Stereo) direct playback, you can output DSD DoP coaxial signal directly, but also through the internal DAC chip CPLD and direct hardware decoder outputs analog signals.

Sound Features
"Perfect restore each music" Music on Hold original vividness and musicality, background static, such as the deep sea, sounds fresh and moist, clean, transparent, full of atmosphere, the sound field broad, extending across the excellent overall sound directly, transparent, dynamic, enough Naiting. the atmosphere, gorgeous and noble.


  • With digital coaxial and optical digital outputs, so that it could be used independently as a digital turntable.
  • With digital coaxial and optical digital inputs, so that it could be used independently as a DAC.
  • Comes with a large thrust headphone amplifier, amp with high impedance and low impedance output port, can directly promote and push a good majority HiFi headphones.
  • Special support pre-function to facilitate users to connect high-powered speakers or no volume control for pure power amp, you can open pre-function menu settings, and then by remote control the analog output volume (Note: Due to AD1955 chip design problems in DSD mode can only be fixed level output, the volume control on the front stage DSD mode does not work, so if your device has no volume control after the class please DSD files into WAV file playback).
  • Amp section with independent analog volume control, can be turned off when using the internal pre-amp function to get better sound quality.
