Compared to the PreMate, the PreMate Plus has a display/control touchscreen on the front panel, an Ethernet port for network audio streaming (Roon and DLNA), and 12V trigger outputs.
The PreMate does not have the "High" outputs (used for tweeters in HD-Active systems), and has only a single digital output (the HDP-4 has four digital outputs).
In addition to the obvious advantage of extending bass response, the DEQX approach to subwoofer integration also highpasses the main speakers. This reduces cone excursion, thus reducing distortion and increasing resolution!
Yes! We can. In fact, we include it for free when you buy a DEQX. Be sure to book your first DEQXpert session soon after receiving your new DEQX to make sure you get the best out of it.
