I agree with Mimesis, the Wiim is a fantastic streamer for the price. I have many different streamers ranging from M210, M218, Cambridge, primare and so on.
But the features and sound quality for the price of a WillPro is unbeatable.
The Wiim Pro also has a built-in equalizer and a room correction that work perfectly well for that price.
But you don't need to buy the Pro+ because you don't need the upgraded analog part, otherwise they are the same.
