@wanderingmoo. In my opinion the compression that happens at higher volumes is related to electronics and room . I can listen at 105 dB in my listening chair after changing electronics ( monoblocks, preamp, dac) from parasound to ayre and cables from kimber select to cardas clear without compression. Speakers and room acoustics are the same . The sound opened up at louder volumes . The performances sound real and there .
Room acoustics and smearing I had talked to acoustic sound company , they sent me an audio file via email and we did the “Matt test” to identify reverb and echo in my room in my listening chair . They then made their specific recommendations. Nothing random, nothing textbook . But based on data collected from my room. You can contact them and they can help you. They work with the decor of the room and waf also 😊. Good luck .
