Transparent Audio PowerBank 2 in wall Power Conditioner?

Anyone have any thoughts on this?PowerBank 2 Inwall Power Conditioner

Same concept



I have a PowerBank 2 behind our TV. It made a noticable difference in picture quality.

I also had two behind my Triton One.R’s for the Subs. They also made a difference.

I removed the PowerBank’s that were behind the Speakers when I replaced the Triton’s with Sopra 2’s. I sold one PowerBank and still have the second. If you are interested, I will sell it for $200.
