I do appreciate the fact that no two cymbals are identical even mass produced.probably not that explosive, because I hope I inferred that it was my own opinion (I feel that...)
but to my ears, it is harder for me to hear the differences between snares than cymbals, because the tunings of the heads presents more random variables from drum to drum...sometimes taking the shell materials, dimensions, hardware, manufacturers, build quality, etc out of the picture for my ear. My 5.5x14 metal Supraphonic sounds exactly like my friends 6.5x14 Tama Superstar maple snare - high pitched Stewart Copland esque sound.
I have a Remo Coated Ambassador batter and Remo Ambassador Hazy snare side head. He has an Aquarian Hi Velocity batter head, and a clear Aquarian snare side (don't know the exact model)....same sound.
BUT, he has a 90's era Zildjian 18" Low China, and I have a 90's era 18" high China, and they definitely sound different...there are no outside parameters that will make those sound the same
it would be interesting to do a blind test to see who could discern the difference in each.
