Synergistic Research HFT's

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.”

You waste you time and money pursuing such tweaks. Put your time and money into the things that actually affect the sound directly, the power and signal paths.  :) 

Define signal path.

Have you considered that room tuning panels, which are efficacious, can be made more artful? You can get them custom made with prints of your choice on the fabric, and can even frame them to appear like artwork. If you had not hear of it, I suggest you check it out. I believe there was a company I saw several years ago that would let you put your image on the fabric. I am guessing that with today's tech it wouldn't be that hard to get a printer that does fabric to put whatever image you wanted on it. 
If you are handy this would not be a difficult task, and could be an agreeable compromise solution if the roadblock is aesthetics.  :) 

I have dedicated 20amp line going directly to my two channel system.  I will have an upgraded outlet.  My wires will all be pasted using PPT goop.  All of my plugs will be plugged into a Inakustic 3500P.  I have upgraded PC's.  I believe I have answered your power to signal path question.
Regarding room tuning panels....it does not matter if I could do a nice custom print.  I used them on my last house but had to place them 12-18' up the wall.  To be effective they need to be at listening level.  In my new house that is impossible as one side is a 16ft sliding window door wall and the other side is the entrance to my house.  
That is why I am asking about the SR products in helping with room dynamics.  Or for that matter, anything else that might help that is not intrusive or large.
