Well.....I figured the L-Cush would add bass.....whenever I put the G-cush on it seems to lose alittle bass.
It also gets a wider soundstage when I use a G-cushion.
So, what jay is saying makes perfect sense to me..
I have tried the G-cush on 4 different Grados....soundstage was bigger....always
Bass was less.....always
I am sure that the drivers make up for more than the pads.....but for the most part.....I feel like I know what to expect from each Grado pad.....just from experimenting.
I agree with what you are saying with the 325's, but when I put the (G's) on the RS's, I thought they had a nice all around bass presence, but it didn't have that tight/slam to it.
And he driver part between the RS/GS is what I'm trying to find out from Jay, being he has both models/pads.
