I ran a DeccaShrub like that as an experiment a long time ago; 2009?. I was just recently listening to the result, and, I was quite surprised. The performance had a contrabass duet at the center of the stage, surrounded by the balance of the Octet players. Even with two big basses passing solos back, and forth, at the center of the stage, the separation and isolation was quite apparent and shocking. You'd think that those two big boys playing hard at under 100hz would want to mono-blob to center, right?,.. especially with a center mic. Nope, great imaging, and even cutting into the rear of the "U" between them.
So, I decided today was the day to break it out again, an try it.
I just tossed it into the digishizzer blender thingy, and, it came out sounding quite nice (except the constant SoCal friggin air condtioning systems,..AHHHHHHH!!! Fuck, I want to kill something). I ran the baffled omni pair at 3.5dB over the CM3-0º, until I found enough of the center player.
Now, for the next rounds, which will be next weekend.
Gude wore his new power cyborg eyes in front of the Consort of the first time. The tenor violinist, center most player, was cracking up the whole time; loved it!
