The compass gave us pause. We attached the power plug to one end of the ground cable and plugged it into our power conditioner. Holger Stein advised us to orient the Ground Cube so the binding post on the cube faced north or south — hence the compass.\u003c\/p\u003e\n\u003cp\u003eOnce connected and oriented, it took about a minute to start hearing what was happening. First: more low-level detail, the signature of a lower noise floor. Musical layers became more distinct. The soundstage deepened and widened. Individual instruments occupied more defined positions in the space.\u003c\/p\u003e\n\u003cp\u003eWe don't have an explanation for why orientation matters. We can tell you that it does, consistently, across multiple listening sessions and multiple positions.\u003c\/p\u003e\n\u003ch2\u003eWhat It Is\u003c\/h2\u003e\n\u003cp\u003eThe Ground Cube is a passive device that connects to a ground point in your system. No power supply. No active circuitry. Holger Stein's approach to ground noise conditioning uses what he describes as quantum physics — a phrase that gets deployed loosely in audio, but in Stein's case represents a genuine design methodology behind the SteinMusic product line that has produced consistent, peer-reviewed sonic results across many implementations.\u003c\/p\u003e\n\u003ch2\u003ePress Recognition\u003c\/h2\u003e\n\u003cp\u003eSteinMusic products have been reviewed by The Absolute Sound, Positive Feedback, and Stereophile. The Ground Cube and related conditioning products have been covered by Positive Feedback with consistent reports of audible improvement in noise floor and spatial presentation.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/rH7gkEXNmzs?si=PRIaEOvx2eapigPk\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.audiodrom.net\/en\/special-edition-reviews\/195-steinmusic-ground-cube-silver-signature\" target=\"_blank\" rel=\"noopener\"\u003eAudiodrom Review\u003c\/a\u003e - \u003cem\u003e\"...Again, compared to other similar [grounding] devices I am getting a heightened sense of being there and an amazing depth of image without the unwanted hi-resolution artifacts like etched transients, too much presence and forwardness, and – consequently – fatigue for ears...\"\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Passive ground conditioning device\u003c\/li\u003e\n\u003cli\u003eConnection: Via included multi-attachment ground cable\u003c\/li\u003e\n\u003cli\u003eOrientation: North-south alignment required (compass included)\u003c\/li\u003e\n\u003cli\u003ePower required: None\u003c\/li\u003e\n\u003cli\u003eDesigner: Holger Stein\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eQuestions about where to connect the Ground Cube in your specific system, or how it interacts with other SteinMusic products?
