The d1-server uses now the quad core cubox-i4. It sounds even much better than the previous monocore cubox. This new server was in demo in 4 rooms last Munich High end show in May.
reviewers feedback are here: http://www.totaldac.com/listening.htm
The previous d1-server can be upgraded to this new quad core processor. The specific cubox power supply board stays the same. The cubox shielding is changed. The Totaldac software for the quad core cubox works with MPAD, and soon with Ipeng8, Airplay and upnp.
Nice to know. Thanks.
Note: accwai, shouldn't you say if you are distributor or a private person?
I'm a private person. Please be assured that I bought my totaldac via the official local representative
