Beskrivning
Since its inception in 1987, Esoteric has been at the forefront of innovation as a high-end audio brand from Japan, continually pushing the boundaries of high quality sound reproduction. The Esoteric brand is known for its outstanding acoustic engineering that has sustained its reputation and prestige, its massive investment without regard to cost, its ”museum quality” craftsmanship, and its beautiful designs worthy of music reproduction. ”Grandioso” is the top model in each product category that has reached the highest level of quality defined by the brand.
In classical music, a phrase that indicates how a piece of music should be played is called a conception motto. For example, ”cantabile” (as if singing), ”legato” (smoothly), and so on. A flagship model should have the dignity and stature of a top-of-the-line product. We named it ”grandioso” (grand, majestic, dignified), which we likened to the motto of classical music. Grandioso has brought a number of highly original innovations to the world of high-end audio, including the legendary VRDS-ATLAS Super Audio CD transport mechanism, the Master Sound Discrete DAC and the Master Sound Discrete Clock, which consist of unique discrete circuits.
Finally, three SE models are now available with new discrete clock technology and improved analog circuitry in the DAC. We are proud of our brand and always strive for the best sound.
The SE model we are releasing this time reflects every conceivable technological accumulation from the time the original model was launched to the present. Enjoy the enhanced presence, dynamics, and beautifully organic and musical textures of the three new SE models.
