^^ The link refers to a US import. So it will work on 110V and you will need to buy a stepdown transformer which adds to the cost. Not recommended because you can get one with warranty for around 22K.
If it is from Amazon.de, then it is 220V European standard. Take a close look at the picture of denon 1612 after zooming, it is evident that it is 220V.hyeah:
