How does Axwell process his vocals?

Everybody knows the Swedish House Mafia are a talented set of producers. I have noticed that whenever Axwell is involved with a track the vocals just sound soooooooooooooooooo good. So warm and great reverbs, delays etc. Now i wasnt sure if it was Axwell that does the vox or if its a joint effort, however i listened to some of Axwells solo stuff and there its the same thing the vocals just sound so crisp. So i was wondering if anyone had any idea how he gets his vocals sounding like this. I have added a youtube link so you can listen and share oppinions :slight_smile:
