I put some cloth grills in front of them for a few listens just to see if Iwas missing anything by not having them. It didn't take very long before I put them away again. These ears like them fine just the way they are. I also played a bit with the attenuators and it didn't take long before I set them back to "0".Yamaha B-2 said:Because to me (the most important ears in this equation are mine) they sound a bit better with the grills on. Have you done some extended listening both ways?
