HIFI Ground Box Review

We've received another stunning review from! Click the link below to get to know more about it!

Link to the ground box - 3io's BlackBox!

This unique ground box is ONLY available at J&K Audio Design and not anywhere else in the whole world. It is made with unique passive electronic circuit that works indefinitely. It is not the mineral based grounding box that is flooding the market now with lots of clones from Hong Kong and China, which may or may not work.
