For all that were so disappointed from the results I have some good news. The unit actually can be great but looks like suffers from some production changes with the last few years of production.
I have two dbx VENU360 that I bought in 2019. One was bought new and the other was used. The first unit that I bought was the new one , and when I measured it with my R&S UPL I was shocked with the bad results I got similar to what Amir measured. I decided to debug it and did small mod to the DAC output with huge measured improvement. I need to go back and see what I did , but is should be very simple mod.
After it when I got the used older one I expected to have the same issues , bit surprisingly the unit measured great from the beginning.
It looks like that newer units are suffering from this issue.
Here you have some measured results with the R&S UPL.
The UPL that I have is analog only. so the driving signal is computer running test wav files and connected to the digital input of the unit under test.
I actually love these versatile units with their great iPad app and amazing easy room correction.
I used them as active crossover, room correction , and easy way to compare speakers when connected to multi channel amplifier.
They are much better than the DCX2496.

I hope later to post the mod I did.
So people that have the unit can have actually a great measured unit , but without actually measuring it they couldn't know.
Very interesting, thanks!
So the question then is: How can one know if one has a good one or a bad one? (my unit, which currently sits unused in the attic, was bought used in 2017)
