When I ordered my DW 5.5 x 14 Bell Brass snare, I wish I spec'd the die cast hoops, instead of the Super Hoop.
I bought the Die Casts to make my snare everything it should have been from the start!
These hoops take a little bit of the ring out of the snare, NOT muffle it, but (to my ears) it seems a little more controlled.
Rim shots are now EPIC! but still quite kind to sticks.
Tuning is now a breeze, there almost no flex in the hoop, so once centred, the head stays evenly on the bearing edge, and an even gap to the shell.
The chrome quality is very good, I have spent hundreds of pounds having classic car parts re-chromed, and this is just as good as those. My only niggle is that there is no DW branding on the hoops, but it's not a big deal.
SUMMARY, If your snare didn't come with Die cast hoops, change them, it will change your sound.
