AXPONA 2011

The Smyth SVS Realiser A8 system is a revolutionary product, found Kalman Rubinson in his November 2010 "Music in the Round" column. After the listener has the sound field produced by his system at the entrance to his ear canals analyzed with tiny probe microphones, the Realiser synthesizes that soundfield with Stax electrostatic headphones. The effect is though the listener was not using headphones but listening to his system; and unlike conventional headphone listening, the perceived sound is outside the head and if the listener turns his head, the sound remains centered. Even in surround.

At Axpona, Smyth were subjecting listeners first to a 5.1 system, then calibrating the Realiser for each listener, then allowing them to switch between the real thing and the version produced by the headphones. Everyone I spoke to, including Ivy Johnson shown in the photo, thought the effect amazingly lifelike; my regret was that I did not have time to experience it for myself.
