Synergistic Research Atmosphere LEVEL 4 Speaker Cables

With the Level 4, you get the performance jump of active shielding for speaker cables without cumbersome power supplies and thick DC wires.  

Synergistic Research UEF Tech uses Graphene based shielding and conductors for the benefits of active shielding in a passive cable. And the results are outstanding.  

I am the original owner. They come complete with all the original accessories - the tuning modules and grounding cable. There is some rubbing on one of the carbon collars from being on a hard floor. The photo greatly exaggerates it - you only see if you you shine a bright light on it.     

Music emerges from a quieter background with higher resolution and holographic realism than was previously possible only from active shielded cables. 

To add voice to your system you have UEF Tuning Modules that allow you to create a customized sonic balance that perfectly matches your system and listening taste. 

Atmosphere cables are handmade in California.
