Just an comment to say that I've now heard these speakers on 3 different occassions.
Putting aside all the ground breaking technology, i.e. user variable speaker directivity, active noise cancelling techniques to remove colouration effects of the room etc, they are flat out the finest loudspeakers I've ever heard when the measure is "the closest approach to the original sound"
No, I haven't heard exotica such as the Steinway Lyngdorf system, or MBL Radiastrahlers, but having heard the rest of the so called high end mainstream loudspeakers (Kef, B&W 800 series, Quad 989's, Tannoys, Kipsch, JBL Everests etc) the Beolab 90's move the game on by a very considerable margin.
And no, I wasn't 'there' at the recording venue re the recordings I played to assess them, re my comment "the closest approach to the original sound", but as a trained classical musician, I played recordings of instruments I am intimately familliar with and play, and to my ears, they got me closer to the illusion of live music being performed, in a true and believable manner, such that they are easily the finest loudspeakers I've ever heard at any price, when the measure is "the closest approach to the original sound"
Definitely not for the mix and match hobbyist audiophile, but for the music lover interested in Hi Fidelity reproduction to the highest levels, they are currently THE state of the art to my ears.
