Placing turntable on top of fireplace mantle?

My room doesn't have a ton of space, my fireplace mantle is very solid and stable, and it does not get hot to the touch (have tested this already)

Any negatives to placing it here? Previously I was using a wall shelf, (pictured in the second and third pictures), but placing it on the mantle would take up even less space in the room. Just wondering if I will have any additional vibrations which could cause reduction in sound quality by using the mantle instead of my old wall shelf.

See pictures (note I just moved so things are a mess and not set up yet):
