I recommend you have your hearing checked with an Ear Nose and Throat MD. I spent a decade swapping out speakers, amps and cables in two different homes, but the sound on the right side of my room was never as loud or as clear as the sound coming from the left. All along the problem was my hearing on my right side.
Now, before each listening session (and sometimes once or twice during long sessions), I pinch my nose, hold my breath and blow out to clear my ears. It works.
