I had an EMM Labs XDS1. It sounds great and is musical compared to other CD / SACD players but there is no comparison between the XDS1 and the Dave / Blu 2 imho. Try to listen to a Blu 2 with your Dave. You will be surprised. You could also dispense with your pre-amp if you have no other analog sources. DSD is soft, diffuse, lacks dynamics and doesn't time.
