As mentioned, we were very fond of the “Ethereal” + “Air & Grounded” settings. The improvement in resolution, contrast, and control almost sounded like a source upgrade. I wish I were exaggerating. At $3,500, it isn’t cheap but if you’re willing to squeeze out that last bit, it’ll be there..." CLICK HERE to check out the entire review

Mike Girardi, The StereoTimes, June 2015:
"...it’s rare to find a tweak that is not in the signal path to have such a profound effect on music reproduction. Once you hear the Atmosphere and how it can affect the music and the listener, you’ll be hard pressed to take it out of your system. Adding the ATM adds improves upon the original intent by adding Advanced Settings which further elevates the overall performance. The combination of the Atmosphere and ATM delivers on its promised performance and showed itself as an essential upgrade to my reference system. Now with the Atmosphere and ATM in my system to stay, critical music listening is possible day or night. Highly recommended."

"...certainly there was an alteration to the soundfield that I could hear, with greater or less spaciousness, greater focus, more or less detail, depending on the option chosen... this was multiplied big time by the addition of the ATM module, however. At that point, four additional advanced soundfield options appeared... each selection has some advanced options that allow you to choose the time of day... definition vs the smoothness of the sound, and the expansiveness of the soundfield... and they all seemed to work in our reference stereo room, as specified, with world-class gear, whose sound I know intimately. Splendid!" CHECK OUT the entire review.
Steve Plaskin, Stereophile's AudioStream.com, Dec. 2014:
"...I found the Atmosphere to be a remarkable product that contributed significantly to the enhancement of the sound of my system. Unlike other system enhancement products that are inserted into the signal line, Atmosphere in no way directly degrades or distorts the audio signal in any way. Atmosphere works by changing the way we perceive our system with alteration of the RF in the room. Being able to select the desired sonic effects with an iPad is equally astounding. Adding the ATM elevates the performance of Atmosphere with Advanced Settings that are easy to implement. While I feel that Atmosphere is one of the most innovative and enjoyable new products to be offered to the audiophile market, its greatest attribute is that it allowed me to become more deeply engaged in the musical experience..."
