You’re talking about sound system output in your analogy. I’m talking about the sound that can be produced by the consoles themselves.
Someone phoning it in on the N64 can produce music that sounds better than a skilled composer making music on the NES. Composition aside, of course. The N64’s sound capabilities are objectively superior to the NES’.
Between the Genesis and the SNES, it’s not so clear. Also, the sample track from the Genesis that you shared is infamously glitched. It’s not supposed to sound like that! Haha
a?
