Okay Randy, I got home and hadn't read the newsletter, but after seeing this I immediately fired up The Planets and listened for about a half hour, both from my normal seat and right at the EP500, switching between 60,80,100Hz and bypass. Since you also have the Mehta Planets, you might check the passage beginning about 4:19 into Mars and a minute or so forward. This seems to reduce the upper bass fullness a bit, but I don't view that as an improvement, since it isn't bloated or otherwise unsatisfactory on bypass.
Curious what Alan's "brickwall" reference meant in more detail. The receiver that I use with the M22/EP500 setup has the usual 24dB/octave rolloff on the sub, which is generally suggested for getting good blending around the crossover.
