I wasn’t sure about the manufacture date of this product as I heard earlier versions had wireless connectivity issues with rear speakers. The unit I received was brand new and already has the latest firmware installed. The sound is awesome I can now enjoy Dolby Atmos and DTX formats that I otherwise couldn’t get with my Sonos arc soundbar since my tv lacked eARC port. Now I have Apple TV 4K and Xbox series X connected directly to soundbars two hdmi inputs and one hdmi from tv arc port to Samsungs eARC port for all the audio formats to work. Sound is very customizable and base has improved as well over the previous 950a model which I returned and kept using the Sonos arc for a year until now.
