Agreed , the quarter mod S are brilliant with both my GradosWhile I agree this is true most of the time for pad rolling, it's an absolute delight finding exceptions to the rule.
Quarter-modded S-cush/HD414 pads, and upgrading S-cush to L-cush on my SR80i, were indispensable when I started this hobby.
Occasional flats on the RS2i, HF3, and HP2 give me bass boost with little drawback.
G-cush on the GH2 and HP2 are nice for the augmented sound stage and treble emphasis.
Geekria donuts are my go-to for the HP2 for a great happy medium between the detail and soundstage of L-cush and the bass of flats.
Maybe it should be said that, Grado knows what they're doing with the voicing of their headphones with certain pads. So unless you're willing to put in time and money, and you're OK with the journey and not just the destination, don't expect better than stock pads.
But it's also comfort, not just sound
