I would add Silverline Sonatinas to the list. My System-Audio's image and stage real well too...but the Sonatinas do this just a bit better :)
Speakers that have holographic imaging on vocals..
As far as 3-d imaging on vocals...I found only a handful...namely Spendors,Vandersteens,and older Spica tc-50s that I used to own capable of doing this...and this includes auditioning Maggies,Thiels,Revels,Logans, and too many more to mention...any thoughts?
