roxy54,
If your post is about the product that tweak1 is posting.....then you are confused. The Music Purifiers (speaker rf filters) are a new product....just released in the last month. I also sell Ground Enhancers....these have been available for 10 years or more. They both produce good results....but the new Music Purifiers are way, way more powerful than the Ground Enhancers.....quite mind blowing for very little money.
