I am surprised the “snake oil” naysayers who have never tried these products haven’t jumped all over this. I started out with one set of 5 HFT’s and noticed an improvement in soundstage depth and width. I followed the instructions for level 1. I purchased 5 more and installed according to level 2 instructions. Another noticeable improvement with one caveat; sometimes I would get some very noticeable inner air pressure. I spoke to my contact at the Cable Company and he said other customers had also mentioned that effect but it went away using 5 more installed following level 3 instructions. I now have a full complement including ECT’s, Wide Angle & speaker kits supplemented with the newest Atmosphere system with the additional slave module. In my opinion the best bang for the buck are the HFT’s but get at least 3 sets of 5.
One of my new neighbors who works for a marketing company with a sound room was amazed the first time she walked into my stereo room which has a wall of windows on one long side, marble floors sans carpeting and drywall clapped her hands and asked me “what is going on in here, this room should have a clap echo”, I pointed to the HFT’s on the ceiling and walls and explained how they worked and she said “I have to get my guys in here.”
