Commissioned by Sony 's Elevated Standard High-End Series to Germany. Only small quantities were produced. These speaker boxes, unfortunately, never received the deserved attention and awards that they would have deserved. Because no one would have thought that Sony could build such an excellent speaker. Sony didn't do it themselves. But have it manufactured in Germany.
With Class A power amplifiers, ideally like the big high-end integrated amplifiers or mono power amplifier blocks, the legendary Sony ES series from the 90 years, these speakers are for demanding, audiophile Elevated HiFi lovers, in terms of precision, clarity and presence, detachment, spatiality and resolution, hardly to be surpassed in the price range up to € 10,000.
Provided that the feeders and power amplifiers also correspond to this class.
Due to the high efficiency, analog integrated amplifiers with toroidal transformer and Class A power amplifiers, with a power of 2 x 70 watts, are already an incredibly audiophile experience on these sound transducers.
