ESS Laboratories USA
Yes, that ESS of Heil Air-Motion Transformer fame from the 1970s. On active display was a pair of the über-cool looking (especially nude) AMT Limited Edition loudspeakers ($5495/pair and pictured nearest to the side walls) which use the Heil Air-Motion Transformer for midrange and tweeter duties, while a 12" front-facing woofer and rear-firing passive radiator take care of the rest. The AMT Limited Editions were powered by a pair of CI Audio D-200 MkII monoblocks ($3500/pair), with a CI Audio PLC-1 MkII passive line controller ($900), CI Audio VDA-2 24-bit DAC ($599), and Sony NS3100ES SACD player following upstream. No one really wanted to talk abut cables here either.
