Playback Design and dCS

Anyone here with any experience with Playback Design MPD8 Dream DAC ? How does it compare with Rossini or Barton or Vivaldi if anyone has compared ?

Some people say that they r better than MSB Select.

MPD-8 Dream DAC is at the similar price range of Rossini. All DSD based design like P S Audio. The main DAC does not have network interface like Vivaldi.
