You might want to try dbx in Sunnyvale, CA.  They make VCA's for automated 
recording studio mixing consoles.  They will probably be best available.
I'm sorry, I don't know the specs.  

The very expensive automated mixing consoles use digitally controlled
motorized faders.  One of the manufacturers is George Massenburg Labs
(possibly known as GML, Inc.) located in the Los Angeles area.
