I will add Royd speakers to this list. They do an amazing job on vocals and the 3D imaging is just amazing.
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?
