I have also had the PD MPS5 and Emm Labs XDS1 for extended listening in my setup. In the end I clearly preferred the Emm Labs, it sounded more controled, dynamic, neutral and above all with blacker backgrounds (really impressive here). The PD is more flexible tough given its array of inputs and 24/192 capability.
At the end of the day I bought the XDS1.
