Want to hear the music breathe? Here’s the best available lung on this planet:

The body construction completely made of non-ferro­magnetic materials combined with a massive slate board optimizes the resonance charac­teristics of PLANCK. The new design with non-visible fixation screws and with a massive and solid aluminium cover pleases both eyes and ears alike.

Converting from digital to analog, newly developed discrete output modules with extremely fast, wide-band high-performance class A output drivers ensure the perfect sonic experience. The current-voltage converter comprises absolutely temperature stable and sonically neutral high-precision resistors.

Our high-precision clock generator eliminates the infamous jitter: PLANCK gets all music data at the right time and with its correct value. And the internal frequency compen­sation equipped with custom made mica capacitors of highest grade guarantees absolute precision in the analog domain.

Also, we gave the digital input section a completely new design. PLANCK uses the same outstanding USB Audio 2.0 technology as Audionet’s famous DNx machines.

In short: In PLANCK we tuned all relevant parts with scientific meticulousness and musical passion to achieve the ultimately possible sonic quantum leap.
