As someone who fell in love with the sound of Apogee full-range ribbon speakers in the early 1980s, I made a point of visiting the room featuring Analysis Audio planar ribbon speakers. Driven by Arion HS-500 amplifiers ($5995/pair), which combine a class-D output stage with a tube input and driver stage, via JPS cables, a track from Patricia Barber’ Companion album sounded sweet and rich on the Omega ribbons ($24,200/pair with external crossovers), but with a touch of color in the mind-bass that was audible on kick drum.
