The Valhalla 2 and the Mjolnir have very similiar outputs into the HD 650. But, the Mojo has balanced outputs exclusively and the topology to provide them. So the OP needs to keep in mind that the Mojo will only work with balanced cans.
Not any more. The Mjolnir 2 has both balanced and unbalanced output for headphones now.
