These Entreq boxes have become the industry leader in equipment grounding and have received many international awards and industry endorsements. Inside is a secret mixture of different metals that ground your signal with a huge impact on sound quality. Entreq have found that attaching drain wires remove unwanted pollutants, stray magnetic currents and impedance fluctuations before they contaminate the sound of your stereo 

Your system will sound more real with a larger sound stage, better instrument definition, placement, improvements in phrasing and subtle nuances are evident. The flow and musically of the system is also improved. Once you have experienced the sonic impact that the Entreq system conditioners have on your system its hard to live without them.

The Tellus II has 3 dedicated outlets and can handle up to 6 devices. The left and right grounding terminals are similar to the Silver Minimus in performance. The middle Terminal is similar to Atlantis Mini 

The Tellus II can be used as a mini Poseidon.
