Ground box trial

We have 1 unit of 3io's Blackbox in New Zealand now for trials. If anyone of you nearby would like to give it a try, please contact us asap.

It's quite easy to use - just plug it to your mains, or connect it to ANY ground point of your HIFI system. The best is at wall plug ground, or power distributor ground.  

Hear it to believe!
