When I originally purchased an HDP-3, I used it in the same way as your forthcoming PreMate - in that case using Shahinian Obelisks (including their passive crossovers) with a Miller & Kreisel MX200 sub.
The fist time I measured, corrected, time aligned & listened was the most significant ’wow’ moment I have had with hifi & even though the quality of my setup is now a long way beyond that, I will never forget that first session.
You should be in for a treat & if you need any assistance, then please ask. As with Al, I used the expertise of my dealer, supported by several emails to Alan Langford at DEQX and then an extensive period of research, questioning and self-learning. Quite a few other DEQX users have also emailed me their config files over the years & I notice that various DEQXperts had originally set them up in a very similar fashion.... which has been reassuring for me :)
