I had filled the stands w sand but I then heard softness in the lower mids..I replaced the sand I got from a northeast store with sand from a Florida beach..the softness dissipated due to the humidity captured in the sand...but as I enjoyed mynturkey sandwich listening to sonny rollins, the soundstage seemed less 3d than experienced in the past...my wife then confessed that she had replaced my real mayonnaise with a low fat version without warning...once I spread on the good stuff and began to listen, the depth of soundstage returned...BUT, there was a harshness I was realizing! I tinkered with toe-in between 42 and 42.325 degrees but my challenge was not solved. I lowered the shades about 18 inches, replaced my stainless steel door knob with wood, repainted my walls with a non gloss paint, replaced the flat head screws in listening chair with Phillips head screws and even cleaned and scrubbed the threads of all the light bulbs in the room....still the harshness! At last, I discovered the challenge. Shame on me for not realizing this earlier! I was not wearing any socks! Of course. I immediately pulled on some 70% wool mid shin, navy blue dress socks from the target and the harshness was gone! Rollins never sounded so sweet! Though I may be noticing some faulty imaging...uh oh.
