Apogee Digital

About Manufacturer

Apogee was founded in 1985 and initially made its name designing filters. Later, Apogee's complete conversion systems pushed the envelope of digital audio quality and solved many of the early problems with digital audio technology. Apogee converters have become regarded as the reference standard for digital audio conversion. Products such as the award-winning Rosetta 800, AD16x and DA16x  have become the modern benchmark by which digital audio conversion is judged. A new generation of Apogee products including the revolutionary Symphony I/O, with its modular design and flexible connectivity,  promise to extend the Apogee legacy and further advance the art of digital audio.
