I mentioned before that earlier models of the CCa included the Stabilized Output circuitry but we has discontinued it because it did not seem to improve results and even appeared to have a negative effect in some cases. I went back and verified this but also built a couple more with the circuitry included.
After further evaluation, the effect on the Stabilized Output on the CCa was and is minimal due to the active compensation circuit in the CCa. However, this aside, in the interest of providing the best output possible, we have decided to include this circuitry at no additional cost.
However, in our cheaper models, I did find that the signal was improved about 10 percent and we have updated them to include this small improvement. This improvement will not increase the cost.
I have not found any advantage to the 90 percent positive pulse except that it feels stronger and therefore might add to the placebo effect. I will continue to research this however and will publish data when I am done.
