Steverino,

I spoke about it a few years back when I was just introduces to the idea of double-conversion class D regenerators. There are ton of them out there. I did tried two of them they were not good but it does not mean that other will not be good. The question is: how many of them you will be trying in order to find the one that works? Be advised that commercial companies (like APC and others) do not have a concept of trial and return – you need to actually buy the unit to try it. I am pretty sure that how that PP cop any was started- they discovered a class D double-conversion regenerator that worked well and then they just optimized it for audio use. It is even possible that they feel that they know why their unit sound good and they over the time are trying to capitalize and improve on it. This is controversial subject and I do not know how accurate would it be but I am sure if you ask them then they would tell you that they constantly and intentionally improve their units. I personally feel that if the very same PP would be design from scratch to be audio unit (with block compartments, shielding, isolation of and separation of duties and etc) then it would be much more interesting performing unit but it is what it is.

So, not is the question: how many random double-conversion class D regenerators you will try in order to find the one that work out for you? I think that whole point to pay to PP, and I have to note that to pay twice more than it would be for a commercial unit with identical electrical characteristics, is that PP assure you that their unit WILL work with audio well. I think it is a legitimate trade of price for quality and assurance of a custom accommodation.

I have one of my client was disposing a fully operational large double-conversion class D regenerator. It was in vicinity of 30kW and was size of large refrigerator and own separate blower. I was able to get it from them for vertically nothing but then I reflected and thought again. Why do I need to do it and buy a pig in a poke with knowing what would be the result if with PP is might have more or less guarantied or at least predictable result? So I desired to do go there.

For sure it would be fun if somebody would do many experiments and try different devises and then publish own reports. I wish it would be somebody else not me. I have made enough of own experiments and spent time and money on the search for better power treatment solution. I find PP is good solution and a comfortable package deal. What I mend by “package deal” is that the company assures the compliance of the devise with audio tasks, presume that user will use audio evaluation methods on their devise, permit in house free trail. I do not if they do all of it now but they did when I bought my first into in whatever year it was. I just picked up the phone, called to their dealer (at that time it was Bob Rapoport, the undeniable douchebag) and get my 1st unit in a few days. That ability to try it at home and the promise of 30 days money back was something that I would never get from any non-audio company.

Do I want more audio companies make units similar to PP? Of cause, that would be great and that would make PP pull the hands out of own ass to compete. Years back I told to PS Audio guy that he need to stop make his badly sounding unit and switch to double-conversion class D regenerators. Unfortunately he did not go for that.
