Power Box DS Sources: Cleanest power for ultimate sound of Box Design components plus 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 DS Sources. It significantly enhances the sound quality of up to six Box Design components, like streamers, CD players, pre-amplifiers and also offers the possibility to connect 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.  

Six standard connection cables are included in delivery. Special highend super shielded connection cables in these lengths are available on request: 20cm, 40cm, 80cm, 1m.  


The following interconnect power cables are supplied in box:  

2 x 9V (1.3mm connector)  

3 x 18V (2.5mm connector)  

1 x 15V (2.1mm connector) - to connect a DC driven Pro-Ject Audio Systems turntable.*  


*Attention: not compatible with Xtension 10, Xtension 12 and the models of Signature line, for those a high power cable is needed (available separately).  


Higher end power cables Connect-it Power DS with superior shielding and transmission are also available for Power Box DS Sources!
