Post Subject: Sad state of class-D regenerators for audio.Posted by Romy the Cat on: 6/4/2014

Well, it is sad but all across internet, and at this site (http://www.goodsoundclub.com/Forums/ShowPost.aspx?PostID=20851) there are comments about pure Purepower service and problems with Purepower units that they "improve". I kind of sympathize with the people about there but I need to admit that my Purepower units that worked fine in my home did work (an continue work) wonderful in my system. I know what people complain about noise from the Purepower unit, I never had it and can't relate to it.

A few month ago I made a friend my, the industry person, to get to himself Purepower unit and it did not work for him. He reported noise, the Purepower did not fix it and then he had problem to get his money back. This kind of ridicules as you want to piss the people like the friend of my the least as if the Purepower unit work for him then he would be able to move a LOT of them. This morning I got an email from another guy who bought new Purepower and has a lot of problem with the unit and with the Purepower people.

Well, it looks like it is an unavoidable pattern and it looks like the Purepower folks are abut over own ability to handle the satiation. I kind of feel semi-responsible as I was the one who was blabbing about Purepower sound perhaps unintentionally seducing some of the - people out there to try Purepower. I was told that Purepower does not allow anymore 30 days how trail and reluctant to return money foe damage units. That is bad. I am sure that among the Purepower units there are some fools who did something wrong and it was not Purepower fault but the avalanche of complain about the company is self-evident that Purepower folks are killing the company. Very sad indeed as behind this very stupid and very irrational behavior that Purepower demonstrate there is in my view a truly remarkable products and if Purepower goes to dark then it would be a shame to lose the product.

In my view the apparent problem that Purepower has make then a good target for acquisition, if somebody would like to try then it might be a good time - the product is still great but I do not think that they have a lot of sale traffic. From a different perspective buying Purepower own would buy the whole legacy of current product and only God know what in there - I am very convinced that a lot of crap in there is not necessary.
I was proposed to make my own alternative to Purepower regenerator. Something with PS Audio-like bells and whistles, completely audio-oriented (means no battery), 5-6kW, full service/performance indication, very reliable, twice simpler design wise, 4 times smaller and lighter. I spoke with my engineers sand they told me that it would take a month to design Purepower-like from ground up and perhaps another month to build a prototype.

There is two problems in this scenario. I personally do not want to commit myself to it full time and I neither I, not my engineer, not I think Purepower for that matter know how to make the unit to sound good. I am very convinced that my guys would do 10 times better performing unit, that will be 10 times more stable and will be all together much better engineered machine. However, I have no idea if it will sound acceptable as I can't form to my engineers the requirement that would be responsible for sound quality. To shoot aimlessly and conduct experiments I have no interest, time and money.

So, what is left for audio people? The example of Purepower conceptually indicate that by means of switching double conversion regenerator it is possible to accomplish a phenomenal sound improvement but... not one resalable makes those regenerators. Some people can look at the part of commercial regenerators for computers. A good let say IBM on-line regenerator of 5-6kW cost about $4K - only good know how will it sound. They for sure do not offer 30 days money back...

What I do think is that someone out there shall reading my post of using own judgment to realize that there is a market for a stable, functional and good sounding Purepower-like devise and unfortunately the Purepower refuse to deliver it. I wish somebody like Paul McGowan from PS Audio enter the market of class-D regeneration but I am sure that he will be killing his analog regenerators as Purepower always were better sounding then PowerPlants, if the Purepower were not faulty. Anyhow, I do wish somebody to pick up the torch and would make relatable and functional class-D power regenerators available.
