I first heard Hungarian speaker company Popori Acoustics' top-line XR1.23 electrostats in Warsaw last year, where their deep bass greatly impressed. On Day 1 of the Pacific Audio Fest, the world-wide premiere Popori's WR1.23 w electrostats ($75,500/pair), which reside one level below the XR1.23s delivered some of the best sound I heard at the show.
