If you look at the polar plots for the LSD2, the Omni pattern is round on low frequencies and quite directional, almost figure 8, on high frequencies... which is pretty common among omni's in general, but I think this is perhaps a big more exaggerated here. I've thought about running the LSD2 with crossed Omni (similar to XY or blumlein) along with my Senn ME-66's. I haven't done it yet, because I haven't had the right time/place yet. Someday...
