yeah - I read the binaural to Bformat section. But the problem is with what they describe there that I don't think it would be any different from converting a normal stereo signal to b format - in fact it could even be a little bit worse. Its nothing to do with Kemar heads - just the fact if you have a piece of software like Dearvr you can pan a sound in a circle and output it as Binaural or FOA or whatever. The problem you'll have with panning binaural on to speaker like they described panned left and right etc is you will get the binaural cues for the left ear hitting both ears and the binaural cues that are just for the right ear hitting both ears thus rendering any "binaural" cues in the recording ineffective - even worse with quad - thats why crosstalk cancellation is built in to transaural systems - but Ive not hear dthat work very well either. I think you're best bet would be to convert binaural to normal stereo and do that for two pairs - quad will always be better than binaural for an installation or just build up a quad soundscape from scratch .And yes I did try what you are describing years ago .
