Mechanical Excellence and Masterful Craftsmanship

The Z1 Plus boasts a robust aluminum alloy housing that effectively protects against vibration, dust, and noise, ensuring superior sound quality in any environment. Its efficient fanless design keeps the CPU and system cool while no fan noise and minimizing electrical noise. Improved EMI absorption with a higher permeability (>120 @1MHz) further reduces internal digital circuit noise from components such as DRAM, CPU, SSD, network interface, and USB signals.

It features a cutting-edge cooling system that incorporates graphene material and a copper heatsink to dissipate heat from the CPU and SSD to the case. This innovative approach maintains a lower temperature, reducing internal noise and creating a spacious environment for optimal audio playback performance.
