The RSX-GS9 is the first in-car receiver to support Hi-Res audio playback and was revealed back in IFA 2015, it features a single din form factor and will support DSD files and Sony's very own DSEE HX sound upscaling technology. Sony officials has emphasized the use of its new Hi-Res audio player to be best experienced in premium and hybrid cars that has great noise isolation cabins, the great sound can also be attributed to the ESS ES9018s D/A converter that delivers 32-bit audio, transcodes analogue audio to an impressive dynamic range of up to 135dB and THD+N (total harmonic distortion and noise) of -120dB, which means you will be able to listen to background music instruments with superb clarity.
