Is DEQX a game changer?

Wondering if any could share their connection setup.  I’ve been attempting to integrate my preamp into the chain, with 0 luck.  I pulled my DAC and inserted the Premate and am not able to get a signal to pass through my preamp.  Sounds/works great without my preamp, connecting my amps directly to the DEQX, but getting the processed signal to pass thru my premamp, no bueno.  It may be something as simple as selecting the correct input, via the DEQX, though I’ve selected “auto” and every input, via the remote.  Any help is greatly appreciated.

Wanted to thank everyone for their commentary and posts on this piece.  I have one coming, should be here next week.  Looking forward to getting it integrated.

Hi Al and thanks for the quick reply.  Your interpretation is correct.  It does sound quite good without my preamp, but I really like the tubes I have in it, adds a little “warmth” to the overall presentation, so I’m not ready to discard it.  The preamp isn’t super finicky, but confirming that the analog out into the preamp should suffice, has me stumped.

Ok, I won’t throw a “solved” in there, but generally the simplest answer is correct.  I wasn’t plugging both XLR’s from the preamp into the DEQX, just one side; which there was just white noise coming out.  Plugging both in makes it work, along with the sub.
