Let me start by saying that these two groups are made out of completely different materials. Cheap cymbals are usually being made out of Brass or Bronze B8 while the best cymbals are made out of Bronze B20 or some mix of high-quality materials.
Imagine like you have apple juice with 100% apple in it and then as the price gets lower you get more water and sugar and less fruit. The end product is similar. With cymbals at the end of this process, you get very little good materials and more crappy ones.
That being said it’s very straightforward how the price influence the sound. For all beginners, I strongly suggest not to shoot for the most expensive series right away. Hitting the cymbal has to do with having a proper technique and except low-quality cymbal materials, the bad technique can cause cymbal breaking.
I would go for some other brands like Istanbul, Anatolian Bosphorus or Masterwork which are not that expensive like the “Big 4” but have decent quality so you will probably get better sound for your money.
Later, down the road, you can pick and chose cymbals you like. Always have in mind that some cymbal series are there for a long time and with a reason.
These are the series like Zildjian A custom, K custom, Paiste 2002, Sabian HHX, AAX, AA, HH, etc.
So, with the price increment you really end up with a better sound it’s just a matter of whether or not you need to spend a particular amount of money.
All the high-quality cymbals have a similar price and it’s hard to get a good deal so go slow sell old cymbals add some extra cash and level up eventually.
