Hi Doc, It's been a year since we have discussed purchasing your intellectual property regarding your "Audio shoe mod"
My investment team has advised me against this as to the limited market demographics. I can see a need for good coupling of ones feet
to the floor but having said that I feel that you have a fundamental flaw in your theory, that is any standard deviation of one's shoe height with the needed coupling spikes or knobs would actually lower the audio sound stage and the WAF factor would be disastrous if spikes were employed on a hardwood floor.
Sorry that it's been exactly a year to get back to you regarding this matter but keep working on it and let me know.
Best wishes, Lee
