Impressions after first E Mat placed inside the sub breaker panel.
The E Mat is attached to the inside of the outer pannel door so it is not exposed to the outside sun and weather. It is not attached to the metal plate that actually covers the circuit breakers.
I have been following the break in process by watching and listening to Blue Ray movies on my AV system. Forty Five inch Sony 4K TV 2017 model with an Oppo 203 Player ( upgraded with Oppo Mod.com power supply, analog sound board, improved cover to transport mechanism, and SR Blue fuse. Audiophile grade wall outlets, power cords, interconnects, and power conditioner are used. The sub panel individual wire connections- hot, neutral, and ground have all been treated with Total Contact . Also all cable connections have been treated with Total contact. All in all a system that has had a lot of effort to maximize the audio and visual aspects to watching movies.
I use the wonderful Blue Ray edition of the movie- The Fifth Element to evaluate changes to my system.
After three days the visual quality is significantly improved. The edges to images are sharper, details like the weave of fabrics easier to see, and the front to back focus of the images in a scene are sharper. There is less blurring during motion sequences. Colors are richer and the black white difference is greater. Movies are more fun to watch visually.
Audio has also improved with better clarity and a better sound stage that matches the size and depth of what is visually seen.
The E-Mat placed at the whole house circuit breaker position has significantly improved my already optimized AV system.
I next will be evaluating the Mat's effect on the separate audio system and the separate headphone system.
After this Mat has been in this location for seven days, I will add Mats to the components of these three systems to see where additional benefits can be obtained.
I have previously tried several Bybee IQSE in my system and I find the E-Mat to be a better product for my audio-visual enjoyment.
