Hardly surprising really.
Why not use Super Stereo mode? After all, it was intended for "decoding" stereo recordings. Geoffrey Barton posted the latest (1985) decoding equations for this. This information used to be in the Ambisonia.com Wiki. Until the Wiki is resurrected somewhere, and rather than repeat Geoffrey's post here, I have made it available on my Google Site at: https://sites.google.com/site/mytemporarydownloads/ Look under Ambisonic stuff. As Geoffrey points out, Super Stereo uses the same shelf filters as B-Format, so that should make things easier for you.
