SweetAnn and Big-Al sound great together (weel, duh, they're intended to be a pair) but some curious duetsa are Kiyoteru and V3 Lily. They take uncommond positions at the songs, being the male the one who sings the upper notes and female the lower ones.

Also, Iroha's powerful voice singing with the soft, cute tone of Kaai Yuki.

And, of course, Megpoid GUMI and VY2.
