Actually they are closely related in that they both use technology developed by Bill Stierhout. His initial designs were marketed under the Quantum Products label using Quantum Resonance Technology. In 2008 Nordost purchased Quantum Products and used the technology is several of their power products. Bill's company Coherence Systems later introduced their ADD-Powr™️ product line which incorporates their latest developments in the field.
