I recently posted a similar topic Lumin, Aurender and Hifi Rose. Check it out there is some good information in it. I have since eliminated the Hifi Rose because there seems to be so many problems with the software. I am looking at the same two units Lumin U2 and the N200.
I like the Usampling to DSD 256 with the Lumin. Does anyone know if the Aurender has a similar feature?
