Thanks for the reply, Pierre! Sounds like I have some more digging to do in the list.
I'm reading through the papers on Jorn's website now. Thanks for pointing me towards his work again. Regarding the ideal Ambisonic playback array, I guess I am really just looking to optimize the 20 speaker system I am using now. At the moment, I use a mix of channel-based and 3OA mixing (Like Dr. Leudar suggested). The Ambisonics work well for ease of panning through the array and for envelopment, but the channel based mixing seems to have better localization and sounds more timbrally neutral. In addition, the phantom imaging between loudspeakers in the vertical and horizontal plane is much better with channel based panning - Ambisonic panning almost sounds as if it jumps between loudspeakers when panning between vertical and horizontal speakers. For reference, I am using Blue Ripple Sound plugins for encoding to Ambisonics and Rapture 3D Advanced for decoding to the array.
