There is no evidence that Silva is a transmuter. In my opinion you cant argue with his personality, because 1. you dont really know much about him 2. Hisoka says, that his method to learn about the nen-type is rather vague.

I would say that he is an Emiter considered the ability he used in the fight with Chrollo. He threw 2 large and very powerful nen-balls. Nen becomes weaker when gaining distance to the producer unless you use Emission techniques. If Silva was a Transmuter the balls wouldnt be that strong. This goes for Xeno too. I would consider Xeno an Emiter because his nen-dragon works at a large distance. Furthermore he is controlling the dragon very skillfully. That means he must have Manipulation skills. If Xeno was an Transmuter, he wouldn be able to controll his dragon.
