After demoing ReMatrix and Phoenix verb think I is gawn go with ReMatrix.
 
Maybe I'm a dolt but Vallhalla (to me) seems on par with Phoenix. Maybe not as good but certainly not only 25% as good (using price as the measurement).
 
But as a convo++ ReMatrix seems to be more bang for the buck over the long haul. 

Valhalla is pretty good. I have the VSTs and look forward to the AAX. They don't have what Phoenix and R2 has but if you don't hear it you don't hear it.
 
ReMatirx seems cool. "It does things you can't do with just one of the other convolution reverbs".
