Post Subject: I am bit confused...and not.Posted by Romy the Cat on: 4/17/2013

I am bit confused with that new report. Under no circumstance I would defense Pure Power, nor anybody want my defense, but the reports I hear juts do not makes sense. If look like Pure Power grade for extra 30% or 50% power with new units, I do not remember how much but it was significant. It looks like they use the same butteries amount, it means the initial voltage in the battery back they have the same. So, they can get more power by running higher current, therefore running the output stages hotter. Nowadays to make an efficient cooling is very simple (BTW the older units had very simple cooling and there was a LOT of room to make it more sophisticated) and if they design a new version then the current they run on the output stage have to be matched with volume and efficiency of the cooling they use. This balance between current and heat dissipation is not try and cut but this is very rudimental engineering task and I absolutely assure you that it was done properly. I just can’t imagine that they place an order for let say 100 units and did not test a fully functional prototype. No one would put the overheating units in production – that would be suicidal or the action of absolutely stupid people. Say whatever you wish about Pure Power folks but I very doubt that would send out the unit knowing that it will overheat – no manufactured will do it. What might hap an is that hifigirlgeek has some kind of specific operation condition in his playback that Pure Power people did not face (presumably 220V swing?) or that this specific hifigirlgeek unit was defective. Just think yourself: would you send the overheating unit out if you know that it will come back? The new PP 2000+ is about year and a half in production, I am sure they sold some of them and I doubt that they sent “experimental” unit out.

I have no doubts that the problems that hifigirlgeek describe are real and looks like the behavior of Pure Power not exactly commendable. Still, from what I heard something does not mach. Pure Power did use customers and guinea pigs testing new implementations but it was with customer’s consent and in my case they did stay behind ether fuckups or the consequences of the discovery process.

Answering the SOS’s question: why are customers still trying the new PP plus units when we have not heard of one good experience. I can’t say about other customers I can say about myself. It is plain and simple: I did not see any power devise that sound as good as two of my units( they are one revision before the Chinese problems but with fixed shielded static bug). A properly operating PP is spectacularly sounding devise in my view.

Would I like to have another devise that would cost a fraction of PP and were less capriccios in operation and support? Of cause I would love to but does anybody know such a devise? I would LOVE if someone would challenge me with presenting a unit that would be better then PP but I do not see a contender. I am not looking for a contestant; it does not mean that it does not exist. Be my guest and search. I spent enough time to “find” the PP2000 and I am consuming in the way the result of my actions. Develop your own power devise, yourself or with some kind of company, let compare the results. My home will be always open for any serious challenges in the realm of audio electricity.
