I liked this headphones.com video, I think it pretty well summarises why there is 'hate for Grado' but also explains how some people still have their reasons for liking them. Only thing I'd add is that, although G cushions do help with comfort, you're trading just peaky treble for peaky
and excessively elevated treble, which I find too unpleasant to listen to.
Sorry
@Resolve for always mentioning you on ASR, I don't have a YT account ... but if you want suggestions of mods to reproduce and measure: shallow cups, taped L pads, and a circle of felt is the best I've managed to come up with. I measured the depth of the rear cup as having an influence on the peak in the mid-range: as you lengthen the cup, the peak becomes broader band and lower down in the frequency spectrum. That's my current theory on why the 2kHz peak is so bad on modern Grados with the deep mushroom shaped cups.
Here's my post on the SR60X review detailing the experiment. My FPC has changed a little since that post, but here's how my SR80i now measures against a HD6XX with new pads:
Disclaimers about FPCs etc. notwithstanding, you can see it's not bad. I like the way it sounds.
The 3D printed cups are the same dimensions as the original SR60/80/125/225 cups (before the 'i' series). Pads are 3rd party, they're sort of a cross between L and F pads in that they look like L pads but are a bit flatter like F pads. I don't know if the foam ring is any different to using electric tape, I just didn't want to damage the foam by applying electric tape directly to it. I'm sure more elegant solutions can be thought up; the principle is to simply have some dense material around the edge of the pad. I can send you the STL files if you want to copy it directly, however.
I've been unable to do anything with deeper pads, like G cushions, that I've been happy with. Thanks!
