That was a good recommendation on reducing the tilt. It typically comes down to your listening distance from the speaker, and as you noted, the tonality/fine tuning. I noticed this when I owned a pair of Magnepan MMG’s several years back, in my listening position having them standing straight up made them much more acceptable, totally, detail, etc. When I moved them to my larger room and sat further away, I liked a small amount of tilt back. What also can change that presentation some is what kind of flooring you have under them/in front of them, carpet or bare floor.
Have fun Jerry, they look really nice, would love to hear them.
