@mijostyn - that looks like a nice piece of gear. Do you know what DSP it is using?
I think the Danville dspNexus 2/8 is an excellent value at $3K, but currently doesn't have software as simple to use as products like the DEQX. You have to be fairly comfortable with computers.
The HW is well built, but the casework is not as fancy as the DEQX Pre 8. The power supply seems to be the weak point and I suspect the DEQX is better (based on what I've seen for their previous products).
I was able to try out the dspNexus on one channel of my main system yesterday. So far, I have only set up the crossovers (96db/octave), adjusted time alignment between my main planar line arrays and my woofer towers, and added a bit of PEQ to the low-frequency channel. My bass response is fairly smooth without any equalization so I didn't apply a lot.
I haven't tried to create any convolution filters yet. And so far, I've only played it from my PC, not from my streamer. Next step is to set it up connected to my streamer and playing both channels to see how it sounds.
