ASTELL&KERN PD10. Flagship Portable Digital Audio Player with HEXA Architecture and Multifunction Dock
The PD10 redefines the concept of a high-fidelity portable audio player, blending cutting-edge technology with a minimalist design inspired by the award-winning A&ultima SP3000M. Its updated aesthetic — replacing the traditional volume wheel with sleek touch-sensitive buttons — signals a shift toward greater performance and flexibility.
HEXA Architecture: Full Signal Separation for Maximum Fidelity
At its core, the PD10 employs HEXA architecture, which fully separates digital and analog signal paths. This layout drastically reduces circuit interference, resulting in a purer, more detailed, and more dynamic sound. It also features dedicated circuitry for balanced and unbalanced outputs, optimizing performance for each connection type.
