My understanding is that the Aida has rear-firing drivers. Imo this calls for somewhat different set-up priorities than for speakers which only have front-firing drivers.
First, you need a fair amount of reflection path length so that the output of the rear-firing drivers doesn't arrive too soon. This implies a fair amount of distance from the front wall. I'd suggest five feet at least, and more would be better.
Second, you do not want the wall surface that the rear-firing drivers are facing to be absorptive because absorption of the short wavelengths (high frequencies) will ruin the spectral balance of the rear-firing energy. You want its spectral balance to be similar to that of the first-arrival sound even after it has bounced off the front wall.
Third, you do not want that rear-firing energy to be too loud. The shorter the reflection path length, the less loud you want it to be. There is a "sweet spot" loudness where the rear-firing energy is wholly beneficial, but any louder than that and clarity starts to be degraded.
If the Aidas were a bit muddy compared to the other speakers, then I would suspect one or more of these factors was in play.
I have not heard the Aida, but have some familiarity with multidirectional speakers.
