Not having compared the two sonically, I can't say. But if balanced operation is important to you, the Freya+ offers two balanced inputs as well as balanced output. There are other functional differences as well. So I would first compare the two functionally and aesthetically, and if you find no clear preference, then you can decide whether the Dialogue sounds 4x better than the Freya so as to justify the price difference.
IMO, much may depend on your listening preferences -- not just source material, but preferred sonic profile. The two preamps will sound different, but only you can say which you prefer. Both companies offer a test period allowing you to get at least a sense of this.
