I use the AVM 60 and find it excellent. Never studied the specs of the AVM 70/90 to see what the differences are because my TV is a 60" Panasonic Plasma, a little smaller than what is available today but the colors are to die for.
The AVM 60 does 4K pass-through. I haven't seen any native 8K media, does it even exist yet?
IMDB has a list of 8K movies but they are all old, not filmed in 8K. I recently saw Avatar: The Way of Water in 3D, the high frame rate scenes were beautiful. The previews also showed upcoming 3D films, one was the re-mastered 1997 film "Titanic" in 3D. The 3D preview looked as fake as the early 1950's 3D horror movies I saw as a kid. Will old films re-mastered to 8K look better or like daytime soap operas, too smooth, too sharp and not like film at all?
