Was not brought more disadvantages

Had it connected to a DM800se. The sound has not improved. Rather each time you switch was a clicking noise of the transmitter. Whether this is a fault in this device or general disturbance, I can not judge, it had also not been tested with other receivers.
My Arcam DVD player I have connected to the test, the original converter and output of the DVD player sounds worlds better. But that was not my expectation, to a 2000 8 year old DVD Player upgrade.
My Arcam rDac provides somewhat more a good sound experience. In addition, no errors occur in combination with the Dreambox with this.

Have him sent back as defective

Conclusion: sound nich so hot, cheap devices can thus enhance hire. Otherwise, a great way to plant the decoupled, eg transmitted interference of a receiver antenna line
