For the high-end manufacturer of hi-fi components audionet, Lechmann Engineering GmbH cooperates to develop and manufacture the housings of the PLANCK CD player, the WATT integrated amplifier and the separate AMPERE power supply. The manufacturing concept of Lechmann Engineering GmbH came into play here 100 percent. From the first sample through to series production, Lechmann Engineering GmbH took over the development of the housing assemblies in close coordination with the customer. The design specifications come from design icon Hartmut Esslinger and were able to be implemented immediately. The high-quality aluminum housings with resonance-optimized, invisible screw fixation are completely manufactured in both mechanical production and surface finishing.
