I'd have to third lgregoir and itsall dark: Verity Fidelios did the image thing, but more importantly, the Sam Cooke you heard was a life-sized, emotive, 104.6 degree man. Don't get me started on Aretha, Janis, or Maria...(Muldaur or Callas).
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?
