You have to be careful when grouping Grados. The SR and RS lines have a common house signature. All the others are unique, including the Alessandro line.
The SR and RS lines are tuned for a pleasing coloration of guitars. They can be fun for that, just the same way DHTs do terrific things with vocals. It's not accurate, but most people enjoy them.
The RS-1 was fun for a few years. I loved it. Then it got to be like every meal tasting the same - I got tired of the coloration. I did keep the HP-2 because it is neutral and has a certain transparency. The HF-1 and HF-2 are fun to listen to now and then, but I keep them mostly because I'm attached to Head-Fi.
Also, OP, Grados aren't for everyone. Lots of people love them. But you're not alone in disliking them. Sell your pair and move on to something else. The perfect headphones for you are probably out there; you can cross Grado off your list now. Nothing to feel bad about, just keep exploring.
I already found them I'm just curious because every metalhead here uses them, so it's very strange that I would hate them. Wanted to make sure I didn't miss something.
