Hi there - you may be interested in this.  Just did a test of converting the 
soundtrack of an Ambisonic full-dome show to binaural using the Ambi-X plugins 
(that has a rotate in the suite that we are checking out for a VR version).  
1st Order > Binaural using 5.1 preset.   Be great to know what people think!
