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 Poseidon is essentially 3 x Olympus Minimus in the one box saving in space and cost. The Poseidon is fantastic for grounding the negative speaker terminals on your power amplifier and your RCA connection on your pre-amplifier. Please do not connect multiple cables to your terminals from your amplifier to the Entreq Poseidon. Soundline will advise you on how to connect your components. The connection of your Pre-Amplifier and power amplifiers to the Poseidon has in our experience given the largest positive improvements.

You can turbo charge the Poseidin with the use of the new K2 or Everest Terminal blocks
