Puritan POWER BRICK 
 
Power Brick Series – PB104, PB104-DC and PBDC-Symmetry
Although representing the entry level to the Puritan Sound with its wider, deeper soundstage, greater detail, greater realism, greater enjoyment, there has been no compromise with the design and specification of the Power Brick Range:

These units encompass the ethos and design elements and expertise that make Puritan products so uniquely special. Embodied in a stainless steel magnetically shielding body, they have 4 x 15 Amps outputs, 20 discrete filter elements that progressively but comprehensively protect against both common and differential mode interference, add cleansed star earthing, DC offset correction (-DC Model), massive three dimensional non-sacrificial surge protection and we present a fabulous introduction to The Puritan Sound for the budget conscious audiophile.

PB104-DC—Power Brick Purifier with DC-Blocking

If you just wish to have DC Offset correction without any filtration the PBDC-Symmetry model will do just this in addition to providing 4 Star wired outputs that ensure connected components each receive equal power
