Move up from single-point stereo to spaced omnis with baffle?

["im_rawes" im_rawes]

I am beginner in recording natural soundscapes, and so far have been using =
an Audio Technica BP 4025 single-point stereo mic. It's easy to lug around =
and fits inside a Rode blimp. Here's a dawn chorus recording made last Sund=
ay:

(There's a funny story behind what the peacock is doing there . . .)

Recently I've heard some fine recordings made using pretty expensive omni p=
airs with Jecklin and Schneider disks.

I'll never be able to afford a pair of, say, Sennheiser MKH 20s, but could =
stretch one day to a pair of AT 4022s plus Jecklin/Schneider disk. Would th=
ere be a noticeable improvement in sound quality over the BP 4025 using suc=
h a set-up?
