Other speakers that excel at imaging include the Meridian M-2 and Snell Acoustics Type A (both dating from the early 80's); the Quad 63 (and presumably its successors, the 988 and 989); InnerSound electrostats and metal-frame Sound Labs; single-diver speakers like Lowthers and such; co-axial speakers like Gradients; Avantgardes; Pipedreams; and Intuitive Design speakers. This list is of course woefully incomplete, but includes speakers whose imaging is especially precise. Personally I place a higher premium on a convincing sense of rich ambience, which would be a different list with only one or two speakers from this list showing up on the ambience list. Disclaimer - I sell a couple of these.
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?
