Components such as high wattage amplifiers require massive amounts of instantaneous AC power to operate as they were designed. Atmosphere Level 3 High Current Power Cables feature UEF and Graphene treated 10-gauge conductors, built-in UEF Inductive Filters.

The Carbon Fiber cylinder houses the Swiss-Made power supply to generates the DC bias necessary for Active Shielding which acts like a mild AC conditioner to maximize your musical enjoyment by eliminating noise from your component’s power supply. This on-board, built-in power supply eliminates the need for messy external wiring and cumbersome wall warts for a clean plug and play solution.

Ultra high current Copper Matrix and Silver Air String conductors increase your components ability to deliver uncompressed music in a life-like holographic soundstage. Tailor the final voicing of the cable with a Gold UEF Tuning Module for added warmth and soundstage bloom.

Basically, we’ve taken our Level 3 Analog power cord and increased the high current geometry from 12 gauge to 10 gauge and that’s before you add in the additional conductors found in the Pure Silver Air Strings and 4th Generation Tricon geometries for a truly noncurrent limiting ultra high current power cord.

Check out my review of the cable here.

I used the red (warmer) bullet for evaluation.


I’ve written plenty about the Synergistic Research. But the very first product that first got my attention was the Synergistic Research Atmosphere UEF Level 3 power cord. At the time, it was unlike anything I’ve heard.

This power cord will make your speakers vanish – and gives you the impression of floating, tangible objects. It’s uncanny in the way it shapes out the porous details and textural cues. It’s weird to say, but you could almost visualize the skin and facial muscles. There are also no gaps or imperfections in how instruments and vocals are present.

Tonally, the UEF Level 3 power cord is cooler – almost a grayscale. What it does best is supplementing the meat with the details. And placing those in a three-dimensional space. The feeling is very physical and visceral. This is all balanced and glued with the proper level of excitement and control. Admittedly, it sounded almost like a DAC upgrade.

This cable seems to do it all. Especially in the way of form, resolution, soundstage, and texture. It keeps things liquid and doesn’t overemphasize anything in particular. There aren’t many cables that are able to provide this much envelopment while preserving the qualities that make music more lifelike.

Who should buy this cable?
If you’re looking for more tangible envelopment – this cable acts like a pair of Virtual Reality goggles for your ears.

If an uncolored sound works for you, not much to nitpick here. It’s cooler rather than warmblooded.
