Keep in mind with the mechanical connections of a full leadscrew system, it’ll never be as quiet as a belt driven system. It’s a lot of weight, a lot of inertia, and it’s all rigidly connected so it transfers the vibrations and resonates. You can try to decouple it from the surface it’s on via a concrete slab and foam, or 3d printed vibration feet. The advertised printing speed of the A/T and F models with the new rails is presented as 100mm/s, though they recently had a beta firmware to push it higher to 125mm/s
Personally, I’ve done 100mm/s with my old A350 with 8mm lead rails (not recommended, but worked for me). It wasn’t really more noisy and pulled it off fine. My F350 with 10W laser slapped on I can still hear it, but I have a couple Prusa machines to compare to, so they’re both louder to me.
