What you want is to maximize direct sound. Reverberation is a key component of recording, as a matter of fact it is typically added to create a sense of space or room to studio recordings, but it should not be something you la Gould look for the room to add, it should come from the recordings. Don’t confuse ambience information with reverb.
I am sorry but what you wrote is misleading...
Reverberation is linked to timing control...
It is not a negative parameters nor an always positive one, it is a parameters which need to be under control but is there always dominating and confusing our perception or not dominating under control and helping our perception ...
It is the same thing for direct sound. It is not always a positive parameter like you suggested...Too much direct sound is negative on timbre perception,spatial cues, listener fatigue, unnatural listening conditions, and if indirect sound comes too quick with direct sound wave : interferences... Etc
Direct sound /indirect sound must ratio must be controlled... It is associated with Sound pressure levels of the speakers and the room and time ratio controls which is needed here , not a qualification suggesting direct sound is good and reverberation is bad .
In a word, direct sound, early reflection, reverberations are three factors and ratios necessary and which must be put under control..."In an excellent sounding listening environment the correct balance of direct sound, early reflections and reverb will contribute to an favourable listening experience"
In a word what we want is optimize the ratio between direct sound and indirect one not increase direct sound "per se"...
Spatial Hearing with Incongruent Visual or Auditory Room Cues

«Here we tested whether a mismatch between playback and recording room reduces perceived distance, azimuthal direction, and compactness of the auditory image, and whether this is mostly due to incongruent auditory cues or to expectations generated from the visual impression of the room. Perceived distance ratings decreased significantly when collected in a more reverberant environment than the recording room, whereas azimuthal direction and compactness remained room independent. Moreover, modifying visual room-related cues had no effect on these three attributes, while incongruent auditory room-related cues between the recording and playback room did affect distance perception. Consequently, the external perception of virtual sounds depends on the degree of congruency between the acoustical features of the environment and the stimuli.
The impression of auditory space occurs on the basis of auditory cues provided by sound waves arriving at each ear, directly from the source, and after bouncing off the surfaces of the environment1,2. Time and intensity differences between the two ear signals determine, in most cases, the azimuthal localization of sounds3,4, whereas the perception of elevation is mainly associated with the direction-dependent filtering effect of the outer ear5. Distance perception has been shown to rely mostly on intensity, the ratio between the energy of direct and reflected sound, and the frequency content of the signal»
Then it is not true that the spatial cues comes mainly from the direct sound of your speakers mostly, and only from the recording , they must be translated, and they are, by the room acoustic signature for the listener ears/brain...
