Sound quality vs. volume


Looking for a bit of expertise here:

I recently made a few changes to my setup and while overall pleased with the results, I’m on the quest for better.  I’m hoping you all can help me diagnose an issue I’m hearing.

When listening to music at lower volume levels - say less than 1/2 total volume, the clarity, imaging and dynamics come across far more coherent and “in focus”.  To use an often over-coined phrase “It’s like I’m there in the room”.  As I start to push the volume up a bit, closer to live-performance levels, the sound becomes increasingly “mushy”.  I know, a highly technical term, but the best way to describe what I am hearing.  The bottom-end loosens up - getting a bit boomy, the crispness of the mid-range and highs fade and the imaging falls out of focus.  These are all incremental with volume until I get to the point where it’s just unbearable.   

I’m no expert by any means but feel it might be room acoustics.  I already know I have a less than ideal setup with a nearly square room (21x20ft) with 60% of the surface covered with clear birch wood paneling. Some things we can’t change (easily).  I do not have any acoustic treatment, just lots of soft furniture.  What I find interesting is that my old setup (Magnepan 1.6) didn’t suffer to such a degree.  Maybe with the new setup there is more to loose?  A mystery.  

For a bit more context:  
Speakers:  Dynaudio Contour 60
Streamer: SoTM sms-200 Ultra
Amplifier: Peachtree Nova500

Within the 20x21ft. room, my speakers are 4ft. from the wall, I am seated 13ft. from the front wall (a bit back from room center). Speakers are 9ft. apart.

Any thoughts?

Hi @geoffkait Thanks for not asking questions about my suggestion, in particular why this would do anything, why it works and what it could reveal about the room/speaker interactions.


In this way I can be certain you neither understand my suggestion, nor why it matters, so I don't need to actually respond.


Best,
E

No doubt that higher volume will exacerbate room reflections and other problems and that the 3' test will tell the tale....room or equipment.
@wanderingmoo as I read your second paragraph room reflections was what first came to my mind. You could try something simple to begin with: use some pillows or cushions around your head to create a sort of narrow listening cone towards your speakers. If that seems to reduce the problem (at least in the midrange and treble) then it sounds like you're on the right track.

Your Magnepan 1.6 speakers would have produced much more directional sound, being a vertical panel and a dipole.
One thing you could try, WMoo, is to place your speakers so that they aim diagonally from one corner to the opposite corner.  Put them out from the wall until the bass is too light compared to the mids/highs.  Your equipment can be on one of the walls if you have long ICs or SCs.  If not, put the equipment in that corner.  Place your listening chair or couch somewhere on the line of those 2 corners facing the speakers.  Experiment with the closeness of the speakers to the chair.  It would be best logistically to have the speakers and stuff where there is no door to get in the way of entering or leaving the room.  

In near square rooms, this often gives the best shot of achieving the best sound you can expect with the dimensions given.  It's free and MAY give you a good boost in SQ.  Nothing to lose trying but a little moving of stuff.  I'd do this and get you sound to the best you can and THEN start messing with room treatments as needed.
