I bought a set of Puresound 14 " 20 strand Brass snare wires to try them. I notice the end plates are slightly angled so when they sit on the snare head the end of the wires sit slightly raised above the snare head. I note the info from Puresound says this is to prevent the snare wires choking , stop snare buzz and to get a better range of tension from the wires. I notice none of the other snare wires I have look like this, ie Ludwig, Canopus - they have flat end plates on the wires. What's your view of this? Gimmick or some real benefit?
