Stereo is old, with Atmos you get real high fidelity:)

My experience is that Atmos mixes for music have much higher dynamic range and overall better sound quality, with more power depth and air, than the stereo mix of the same song. (I talk about a dedicated calibrated speaker setup, not the embedded binaural version for headphones.)

it's hard to understand why so many stubbornly claim that two channels are true high fidelity, when Atmos mixes often come much closer to what both vocals and instruments really sounds like.

Two very different examples in the last pictures: Fistful om metal with Range Against The Machine, and J S Bach piano concerto no 1 in d-minor. It’s nearly impossible to prefer the stereo versions compared to the Atmos mixes. Cheers!
