I agree. I'm one who like expansiveness and separation. Around here, the gcush is described as something that opens the sound a lot more on the 325i so I thought they'd be perfect. Turns out it just felt super hollow and empty to me. The stock pads are completely my preference on these cans, but only after forcefully softening them up quite a bit through constant hand washes.
Good way dot describe the way I felt they sounded with the (G's), hollow.
I prefer the (L's) on all of my Grados by far, but the TTVJ flats sound good on the 80i's, but I still prefer the (L's) on them and didn' t like them at all on the 325is's or the RS1i's.
