I have spent many months dissatisfied with what I was hearing. I will spare the details, but I had concluded that my room was the problem.
All this time, I made many adjustments to my listening position. However, these were all minor adjustments. I had taken the "equilateral triangle rule" as a given and only made changes of 1 or 2 inches.
Today, I got fed up. I moved my listening chair back about 2 feet. Well....holy hell, this changes everything. Bass has heft, images are more solid, soundstage is more realistic.
I learned a lesson, to not blindly follow my assumptions. In this case, it was learning to think outside of the equilateral triangle box.
I am on cloud nine and was inspired to post.
