Yes, I agree nasty sounds. I have lived on a lathe for the last dozen years and I know what they should sound like. And at rpm it is much louder than it sounds on the video. Just not sure what to do about it at this point. And I feel now that after maybe 20 hours of running, it sounds worse. Very confusing, as that is a different headstock than the first headstock. They sold me that under the agreement they listen to it first. But unfortunately that and the next spindle had thread issues, too. Buried earlier in the thread, when I switch headstocks, the weird sounds follow the headstocks. My old headstock on the newer lathe sound absolutely fine, so to me that means it has nothing to do with the motor in terms of noise. At least that is the way I read it. And the motor sound fine in the lower range at full motor rpm. And the noisy headstock/spindles sound exactly as awful on the older lathe. I do wish you could hear it in person, as I think you would feel my pain more than just a little youtube vid. And why I don't want to use that lathe for my work.
