Description

The Black Ravioli Groundworks SA (Signal Array)  is a new design of grounding device which drains away the un-wanted energy inside your chosen equipment. Be it a music streamer, DAC or even phono amplifier. The effects are easily heard. The unit has 3 outlets so 3 items can be connected at once. 

Cables supplied can be terminated with a variety of terminations including spade, usb, xlr, hdmi, rca and more.

 

…………………………………………………………………………………………………

I must say I am pleasantly surprised by the black ravioli USB grounding box.  Mr J. Mumo – Jan 2020

The Eflos gave me an instant hit of impact and even greater dynamics. Mr M. Taylor – Jan 2020

    TRENDING MAINS

    The inconsistency of the UK mains supply is almost legendary: at 7.45pm most weekdays 20 million kettles are boiled, the strain on the national grid is huge with voltage stability suffering as a result. Our mains products will help you battle the vagaries of the country’s mains supply and get the best from your hi-fi or AV system.
