Do you happen to have a link for those pads by chance? One thing about the Grados, they can be tweaked heavily just by swapping the earpads for ones with a different shape. I bought the RSII's and didn't like the lack of upper-bass punch (I think part of it could be the fit... My ears are a little small for those, so they don't make a good seal), plus the upper-mids and highs seemed a bit too much, so I tried swapping the pads with my SR80 pads, and voila, there was my upper-bass punch. So, I decided to make the old "quarter mod" hole a lot bigger, but not quite as big as the hole in the center of the RSII pads, and that made them just right. Attenuated the highs a hair compared to the RSII pads and solved the upper-bass issue. I use mine a lot. They sound awesome through the headphone-output of my Fisher 800C, plus they also do well through a simple portable device like my Kindle or my Dell DJ 20GB player.
