Well going from what look to be Avalons to DeVores will certainly be an awakening. Completely different DNA. You have a problem with the placement of your speakers. They are far too close to each other. If you could bring them further into the room and put a greater distance between them this would help a great deal. Great looking room just not particularly audio friendly at this point. Something to consider is spending some time and a bit of money on the acoustics before changing speakers or any component. Room treatments are easy to make and there also exist a great many premade items. 

The position seems strange, but it is the result of a year of micro-movements of the speakers. If I increase the distance between them you can hear the music coming from one speaker, whereas this way there is more perspective fusion.
In the past I also had a MiniDSP, but then when I did the acoustic analysis it turned out that the Indra's performance is very linear and there are no holes or emphasis, so I removed the MiniDSP... 

I have the pure audio project duets only 3ft out from fr wall, they are great. Sidewall reflections less of problem also. I had Spatial Audio OB before this, like a gateway to OB. But Pure A P a cut above.
