Small room acoustic is not great Hall acoustic, or even studio recording acoustic.. These three are three completely different acoustic environtment for the goal we want to achieve...
These are completely different acoustical field of experience...You are wrong here, because you confuse small room acoustic and studio acoustic and great Hall acoustic ... Sorry .. Same physical acoustical Laws but completely different applications...Do you need a blind test to catch the deep difference in contextual applications ?
if i did not have adressed my small room by balance control of first reflection and diffusion and absorption, if i had not used a grid of Helmholtz resonators but only your DSP my room soundfield instead of being my greatest sound experience, so imperfect it was ,would have been horrible...
I am sure of two things just inspecting your room in a photo...Your sound potential clarity and transparency will be better than mine BECAUSE OF SUPERIOR COMPONENTS DESIGN at way higher cost , especially the speakers compared to mine...but your soundfield is probably not filling the room in a balanced way with for example in the opera recording of Kurt Weill TEST IT WITH HIS :

here the soundfield in my small room all along the album go from beside my ears as with headphone to all around me IN THE ROOM , behind and in front of the speakers, at different times , and distributed all around at some times, it is relative to each album moments...My SPEAKERS DISAPEARED TOTALLY... This recording is TOP recording for sure by a genius ... I know you dont listen classical but we must begin someday... 😊In my room the soundfield of my 600 bucks system will beat yours if i look at the atrocious way you treat your room acoustic ...And your speakers are better than mine with better frequencies responses.. bUt a soundfield is not created ONLY by frequencies responses, it is created by interaction with the room and the specific EARS of the owner... We dont have the same ears filters and structure and training history ,did you know that ? 😊
i am not an acoustician , i just experimented 7 days each week non stop for one year, because it was fun and it was my hobby being retired ..i learned a lot PRACTICALLY not only by reading equation by specialist and calling it done with a DSP , i experimented too ... By the way i used japanese research among books and papers,for example also Toole recommending using first reflection positively in SMALL ROOM about reflection and immersiveness to guide my experiments...
By the way it is related EXPERIMENTALLY , in each case differently, to the specific ACOUSTIC GEOMETRY (form) AND TOPOLOGY (doors+window) AND TO THE MATERIAL specific CONTENT OF THE ROOM and his acoustic properties (wood do not act as fabric clothes or animal skin etc) and it is then related after all that to TIME AND TIMING hearing and measures it is not related to your OPINION AT ALL and to your toys so useful it can be as a tool...
Contrary of what you said mocking those who informed themselves on the net ALL TOP RESEARCH PAPERS ARE ALL ACCESSIBLE FREE ON THE INTERNET for anybody with a brain...
I just argued with you about your ignorance in ecological hearing theory to balance Fourier theory and their relation to measures evaluation of qualities of sound reading among other papers an unpublished master thesis and papers i discover on the internet..
😊
In a nutshell, the most preferred treatment was no treatment
You are wrong here, because you confuse small room acoustic and studio acoustic and great Hall acoustic ... Sorry .. Same physical acoustical Laws completely different applications which must be discovered by some human ears of an acoustician and applied differently in each different acoustical environment...
If i had listened to you my small room would have been what it was in the beginning , horrible and atrocious, before i used my balance treatment with the right ratio and location between reflection/diffusion /absorption and before i used my MANY Helmholtz resonators mechanically adjustable and tuned resonators HOMEMADE distributed at critical location...... All that by my EARS..
No cost...I used garbage in my basement and i bought some tubes and cheap materials..
i am very proud of my room at the time...
i lost it...
And after 6 months of experiments and the right headphone i recreated a three D. room filling soundstage OUT OF THE HEAD, if the recording is good as in many CLASSICAL recording ... Studio recording did not gave the same spatial impressions..
Your friend is right and it is MY EXPERIENCE not by applying DSP but by experimenting:
The second issue not readily evident in the room response though there are some indications is the strong reflections from the very close side walls that will arrive both close in time and relatively high in power compared to the direct response. Yes it is correct that your speakers are well designed with smooth off axis response hence this won’t cause any weird tonal issues making assumptions about your wall materials, but back to the precedence effect, it will affect imaging, and while side wall reflections can make the image seem more expansive and the result pleasurable, when the wall is that close the result is invariably negative. You may not trust audiophile listening reports, but in similar situations, almost without exception where an audiophile was required to place their speakers near side walls, the addition of appropriate acoustic panels resulted in a significant perceived improvement. Anecdotally, you will not find a large professional studio with speakers placed that close to a side wall without use of acoustic treatments.
I won’t say it is universal, but it is almost universal that treatment of first reflections in a small rooms is recommended by professionals. Unfortunately, there has not been extensive research on this topic to draw on and what does exist is mainly around speech intelligibility, however, Brett Leonard in his PhD dissertation did some excellent work showing effects of a rather early intense reflections on perception and even the variability of that perception across music genres. Your position does not appear to be based on the fundamental science, available research, or professional recommendation.
