Is DEQX a game changer?

Yes...

P1 - configure as ’single amp with stereo subwoofers’ & use a (new) full range measurement & calibration without subs. Disable the subs in this config

P3 - configure as ’single amp with stereo subwoofer’ & use the calibration you already have. Enable subs in this config.

In my setup, bass goes down to 16hz -2dB which I’m happy with. You mention the screen - funnily enough I have it disabled, too much of a distraction when I’m listening in a darkened room.

If you go active, try Open Baffle because the transients they can produce give sense of realism I haven’t even experienced with horn speakers. At very high volume, drums ARE drums & it’s almost impossible to hear the difference between a well recorded acoustic guitar & the real thing.

DEQX measurements indoors can produce great results but done properly outside, the results really are in a different league. It is worth the effort.

So I got the hdp5 and installed the Dave. Sounds pretty good. I tested the Dave without the deqx in the chain and lteffered the deqx on its own. With the deqx and Dave it sounds very transparent. I'll need a bit more time with it together. It really showed me again how good the deqx is.

I still have the subs running seperately from the deqx. Do you think it will sound better as full range into the Dave? Alan from deqx seems to think I would get worse results going full rangez even though my speakers are designed to go full range without the subwoofer rca plugged in.

On a side note can the deqx delay the subs by a full 1.5seconds? I need to know because the mscaler delays music by about 1.5seconds and need to know if the deqx can do that if I keep my subwoofers in the chain? 

I agree with Alan, it gives the opportunity to place the subs in order to manage room nodes better than using just a pair of full range speakers. 

However (I'm not at home to check this at the moment), I'm pretty sure you could not add as much as 1.5 seconds delay to the subs. I believe the max available is in milliseconds so this probably means you could not use them with music.

Question.

Do you find the DEQX output level to be low without increasing the gain on the DEQX control panel?

No, the only increased gain I've set via the control panel is volume matching for two subs to main speakers on an HDP-3 slave processor.

The master HDP-5 has no gain adjustment - most listening is within the 'blue' light range on the front display, or 'pink' for higher volume, only occasionally needing 'white' when using a lower output cartridge on a turntable or if I want extreme volume levels.
