Similar models, but different purposes
If you compare the technical features of the Sony A8H OLED from 2020 with those of the Sony A9G from 2019, no serious difference is noticeable at first. At second glance, however, it becomes clear that the manufacturer is pursuing different intentions with the models and thus also addresses different target groups: The A9G can be used as a central loudspeaker in a surround setup by connecting it to a receiver via the built-in speaker connections. It has a very low, central stand. This does not allow a soundbar to improve the sound, as this would cover the lower part of the panel. Therefore, the use of a soundbar is only possible with wall mounting. All in all, the A9G can provide a real home cinema feeling.
The A8H on the other hand has height-adjustable feet on the left and right outside, which in the higher setting provide the perfect space for an additional soundbar. It also has the newer OS Android 9.0 Pie installed, which works much better than its predecessor. Both are on the same level in terms of picture quality and motion handling, but the A8H is much more of an allround model. The purchase of the A9G makes sense if you want to use the appropriate surround setup and bring the cinema feeling into your living room. Both TVs feature Sony’s Acoustic Surface Audio, which enhances the 2.2 channel speakers by actuators that vibrate the screen. The A9G has two of these actuators, while the A8H has only one. In addition, the A9G is also available in 77 inches, unlike the A8H.
