Hmmmm, it would be disappointing if I will be forced eventually to return it as it would make me to look further for some similar solutions. I have seen in APS' the results that I very much appreciate. I juts need to get out of APS regenerator something that it should do according to it’s intend and it's specification. I dod not see why it shouod not do it....
To my big surprise the D-pulses do not make me nervous. If you look at the D-pulses at 2% load then they even larger then at 70% but at 2% it sounds exceptionally good. My objection is Sound not the intellectual satisfaction. If I need an intellectual satisfaction I have a power plant: the PP has a perfect wave across all range and the order of magnitude less distortions – well the PP is also sounds not acceptable.
In fact if to look at the subject deeper then it might be some rations to have D-pulses. Let me to explain. In the power regeneration we care only about the 60H fundamental, right? The PurePower uses somewhere around 20KHz pulses that should be filtered after the D-amp (like DA converter). So, the unit has a filter, let pretend at is at 100Hz, wherever order… The power lines have some noses at hundreds kHz and those noises might be good filtered by the D-amp output filter. At the perfect world it would be nice to have this unit properly operating and then try to tune the out filter, presuming the fixed 70% load of class “A”, writing a perfect Bessel curve and perhaps experimenting with the steepness of the filter…
Frankly the more I think about this APS unit and its idea the more and more I coming to the observation that if it this type of regenerator is made to functions properly then it should be extremely interesting solution.
