Compared to the HDP-4, the HDP-5 has a display/control touchscreen on the front panel, an Ethernet port for network audio streaming (Roon and DLNA), and 12V trigger outputs.
The HDP-5 has an additional set of analog outputs for high-frequency drivers, so it can be used in HD-active configurations i.e. bi-amp and tri-amp. It also has a full set of digital outputs for connecting external DACs (the PreMate Plus has only one, for the main speakers). Finally, it has an unfiltered digital "through" output for use in master-slave configurations.
Yes! The HDP-5 is a superset of the PreMate Plus. To use with conventional passive speakers, connect the power amplifier to the Mid/Full outputs (RCA, XLR, or digital).
