Our Verdict

LG SN9YG

LG SP9YA

The LG SP9YA is the upgraded version of the LG SN9YG, and it has a better overall performance. The SP9YA has a better soundstage performance, and it gets louder. It also comes with more features, including more EQ presets and an LG TV AI Processor advertised to create a more immersive sound with compatible LG TVs. It supports Apple AirPlay too. That said, some users may prefer the SN9YG's built-in voice assistant support, while the SP9YA requires a third-party device to use the voice assistant.
