It contains no filtering and no active circuitry, because Nordost's view is that anything in line raises the impedance of the supply; what it does instead is organise the grounds. Every outlet connects to one central star-earth point, and all but one outlet, the Primary Earth position, have their ground impedance raised so that components are isolated from one another and the designated component sees a direct path to the wall. A dual-level board keeps ground traces away from line and neutral, and a resistance sink damps eddy currents.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px\"\u003eThe QB8 has eight US outlets in a mechanically tuned extruded aluminum body, with an external ground post for a QKORE or other clean ground and a dedicated fuse. Reviewers have found the effect direct: Steve Dickinson of hi-fi+ noted significant benefits to timing and the resolution of fine detail, and Neil Gader of The Absolute Sound wrote that the sonic results make themselves known immediately.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 20px\"\u003eChoose the 15 A version with an IEC C14 inlet or the 20 A version with an IEC C20 inlet in the selector, and match it with a Nordost power cord from the wall. The QB8 suits a full system of separates, with the power amplifier on the Primary Earth outlet. A QBASE Stand Mount is available for use with Sort Kones.\u003c\/p\u003e\n\u003ch3 style=\"margin:0 0 8px;font-size:16px\"\u003eKey technologies\u003c\/h3\u003e\n\u003cul style=\"margin:0 0 20px;padding-left:18px\"\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eStar-earth topology.\u003c\/strong\u003e All outlets ground to one central point, removing conflicting signal and ground paths.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003ePrimary Earth.\u003c\/strong\u003e One outlet keeps a direct, low-impedance ground;
