got the PS500 a few days ago and was, at first, a bit disappointed.
but, either they seem to be improving, or my ears seem to be adapting. isn't that always the case?
anyway, a good buddy of mine had a pair of g-cush pads that he wasn't using.
i took them off his hands, and am trying them now.
so far, in my experience, they do a nice job of making the grado sound a little bit deeper, slightly brighter, and with slightly better definition through the bass.
this was my main issue with the PS500 out of the box, that the bass was sort of one-note, and the quantity was a bit too much at times...
things seems to be sounding pretty good right now, though... we'll see if it makes the cut.
there are some heavy hitters in my arsenal that the PS500 is going up against...
