Description:

• The QA360 MOD is a mass production version of the QA360LE, It's circuit and material and QA360LE is exactly the same, only the production process will be different. It is based on the QA360 with improvementon the sound. 
   
• The QA360 MOD's sound of approaching a limited edition (limited edition can at least reach 97% of the sound quality is generally not AB will be obvious).
   
• Compared to the QA360, it’s quite obvious that that the QA360 MOD is able to produce a noticeably cleaner and more textured sub bass. QA360 MOD is have a more thicker warm mids, and more precise's Imaging, and a more background's dark, has a great sense of impact and musicality, and more retrieval of details .
   
• Our target: “Perfectly and accurately recovery for the music recordings, and deep dark background”.

The Single Threaded Software Framework

QA360 MOD implemented QLS-HiFi’s unique proprietary technology – the single threaded software framework. This technology ensured ultra-low jitters and high accuracy in playback of digital music by occupying the whole CPU with the single music reading and decoding program during the music playback.We keep it simple as always for supporting the simplest SD media cards only, however on the other hand we make every attempt to improve the back end qualities so providing the best value to againstthe priceto the true audiophiles. QA360 MOD is the continuing persistence in pursuit of our belief on HiFi equipment development.

24Bit / 192KHz wav and DSD Support

QA360 MOD supports Studio Master wav files in 24Bit / 192KHz and DSD64 / 1Bit / Stereo. DSD files can be streamed out of the digital output in DoP format, and hardware converted to analog singles directly through the internal DAC as well.
