Perpetua is DITA’s 2022 Dream-Class, flagship product. A celebration of 10 years of DITA. It is a self-examination of what it means to evolve and mature as a brand born out of a love of sound and music, and a desire to execute these to perfection.
The PPT-D sits in an acoustic chamber of titanium specially optimized for its size and function. Maximizing both the 12mm driver’s potential and the metal’s sonic qualities. A continuation of the tuned acoustic concept used in earlier products such as the XLS.
DITA is honoured to have Kondo Audionote Japan, one of the pre-eminent figures of silversmithing in traditional HiFi, onboard the Perpetua project as the provider for its internal wiring. Perpetua's Internal wiring uses Kondo Audionote Japan’s signature 99.99% pure silver. Aged and annealed in a highly secretive process, then carefully drawn into strands and soldered at an optimal temperature onto the respective contacts.
The Coil/Over cable uses Length Specific Geometry: Utilising varying lengths of signal and return paths to reject micro interference. While difficult to design, it is even more difficult to produce. The nonlinear positive and negative signal leads are arranged in a coil-over construction of 6mm pitch. Resulting in a unique, “wheat-ear” like appearance that aims to reduce noise and distortion.
