Having heard DI just once at Capital Audifest this year, I wonder if the shortcomings you describe might be attributed to the listening position being only 9’ away? In general larger speakers with multiple drivers need some distance to the listening position for everything to gel properly especially in regards to detail.
At Cap Audiofest, the DIs were set up in a average size hotel room, not particularly large and I’d estimate I was at a similar distance listening.
The only negative I noticed as I cited in comments here shortly after were I could locate the drivers location with eyes closed meaning that imaging was not fully gelling. I would expect better results in that regard with more distance from listening position to speakers. A larger room would have suited the fairly large DIs better in general I’d say.
Just a thought. It may be more an artifact of limitations in setup in a particular room as opposed to an inherent problem with the speakers.
I tend to shy away from most any larger "tower" design speakers in closer quarters these days based on past experience trying without total success to get those to gel properly for both imaging and sound stage in closer quarters along the lines you describe in your case. Especially towers with multiple drivers for the mid and higher (more directional) frequencies that are not located in close proximity to each other.
