The MFU design is based on the notion that everything including AC devices influence the sound. The design is a purely functional one based on elegant simplicity principle, which means that the music actually becomes more dynamic, convincing and beautiful! All this is only possible if the design employs the specially selected passive materials and components that were harmonically matched to provide the best possible sonic result. The wiring inside employs the same signal conductors we use inside all our cables and our assembled products.
