Power Box MaiA: Cleanest power for ultimate sound of MaiA, plus 3 components and turntable!  


It is a proven fact that a power supply is a very important part of the audio path and significantly contributes to the sonic quality of an audio product. In order to offer the possibility of improving sound quality, we designed our linear power supply Power Box MaiA. It significantly enhances the sound quality of MaiA integrated amplifier and additionally three Box Design components, like streamers, CD players, etc plus a DC-driven turntable.  

A linear power supply consists of a massive toroidal transformer with shielding between primary and secondary winding, which acts as an isolating transformer and avoids penetration of interferences from mains into the audio component. The built-in transformer has a much higher power reserve compared to the standard power adapter. It has very low output impedance and in combination with large filtration capability it can easily manage all power needs. Sound staging, darkness of silent backgrounds and small detail resolution will improve strongly and contribute to a far better overall performance of each component. Five standard connection cables are included in delivery. Special highend super shielded connection cables in these lengths are available on request: 20cm, 40cm, 80cm, 1m.  

Advice: To avoid magnetic interference do not stack audio components and Power Box MaiA!
