Sony Media Receiver RSX-GS9

The Sony Car Audio RSX-GS9 supports Native DSD, which is the first car audio to record a sound signal with a 1-bit digital pulse density, so that DSD data is not converted to PCM when played back, so that the original sound file can be faithfully reproduced without distortion.
The Sony Car Audio RSX-GS9 supports LDAC codecs up to 3 times the transmission bandwidth of existing Bluetooth codecs, making it easy to enjoy HRA-quality sound better than CD quality sound wirelessly.
Supporting DSEE HX technology, which can upsample a CD or lossy compressed sound source to high resolution audio levels, the Sony Car Audio RSX-GS9 restores the lost sound field in the original sound and boosts it to a high resolution audio level.
The front panel of the Sony Car Audio RSX-GS9 is made of 14mm machine-cut aluminum and minimizes unnecessary vibration that can affect sound quality. It is designed as a 0.8mm high rigidity dual layer chassis to suppress noise generation.
The Sony Car Audio RSX-GS9 supports high resolution audio through in-car media receivers, supports Bluetooth and one-touch NFC ™ functionality for easy wireless connection to a variety of mobile devices.
The RSX-GS9 is considered to be the best car music system on the planet.
