Reply to Advice on Modular Synths

Hey everyone.
First, I'd like to thank anyone who is reading this and posting their feedback. All help is greatly appreciated.

So I've decided that I really want to learn how to make electronic music. I have FL studio but I've decided to buy a book on synthesizers and start my journey by making a rack of modular synths. I really want to know the ins and outs instead of relying on a computer program.

I've read up a bit on the different types of modular synths but I just don't know where to start. I like songs like Awooga by Calvin harris or anything by Sidney Samson, Afrojack, Deadmau5, Feed me etc..
Are there specific synths that can help me achieve these types of sounds? And if so which company should I stick to?

Thanks again
