Considering the secretive nature of the majority of producers and audio engineers, I'm sure their are quite a few out their, especially in other genres of music, but you would never know because most keep their methods close to the vest if you know what I mean. Their is plenty of dance music that has what most would consider a "pro sound" that has been completely created ITB. As many have said - it's not the tools, it's the skills of the person using them (sure nice tools might help, but only to a point).
