I'm auditioning the C390DD this weekend as well. Look forward to reading what your thoughts are. So far all I can say is WOW! I auditioned at my AD's store between thE C390DD and the NAD c375bee with the Rega Dac. I've found the C390DD a little more open, detailed and laid back which I didn't expect. Extremely impressed so far. I've been auditioning quite a few amp/dac combos and haven't found anything to deter me from purchasing the C390dd.
Using older Dynaudio Audience 52's and I've never heard them sing like they are. I'm newer to the audio world but have listened to a lot of high end gear, and IMO this beats anything out there at this price point. Only issue I have is the "newness" of the product.
