Purepower 2000+ and 3000+ actual availability???

I tried a Purepower 2000+ unit in December 2012 after the demarcation (time)line in your posting above which stated you had fixed all defects. It was a newly finished unit at the time and the system hum problem (and buzzing through the speakers) in my system caused me to ship the unit back to you so I would suggest that you are not 'complete' on the + units until you remove the hum and buzzing effect that occurs when you put these units into high-end systems that are stable and do not have these issues. Furthermore, I already utilize a 2000 (non +) unit in this system for the last 2 years and do not

I look forward to you answering 1 and 2 on another thread as I'd love to test a unit that does not manifest the humming and buzzing in my system so that I can upgrade from my 2000 to a quality and completed 2000+.

Purepower, the name is ozzy not oxxy.
Something doesn't sound right from your new postings and the long long string of negative comments on your products and service.
I would think you would fix all of the defective units BEFORE you sell any new units. That would show us how determined you are to be a viable company.

I received my Pure Power units back in the summer of 2012 (the second one may have been in the fall). I have posted before on this thread, if anyone wishes to read about my experience. The bottom line, though, is that I have had no hum issues; and I would not want to live without the PP+ units.

Hum from speakers.

Since the introduction of the PurePower+ There have been 2 customers who suffered from hum that appeared in their speakers.

By definition, hum emanating from the speakers represents an unwanted signal that has entered the audio signal path through one of many possible routes. In the particular cases that the hum appeared after installing a PurePower+ unit we very strongly suspect the path is through a ground loop. We suspect ground faults because of our prior experience with similar symptoms over the years that were resolved by finding and eliminating ground problems.

We do know that there is no inherent electrical characteristic of the PurePower AC output capable of affecting the audio signal through the AC supply. Nonetheless we returned both units to our factory to be absolutely certain they were operating perfectly. They were.

We suspect we have not convinced these now former customers that with perseverance, the cause of the hum could have been found and eliminated through the right diagnostic method and signal tracing tools. Unfortunately we could not resolve the issue and they are now operating without the benefit of our product. I think it is fair to say that both expressed a clear wish that they could enjoy the PurePower benefits – hum free. Thus, they are hoping we will be able to modify our product in some way to solve the problem.

For our part, we wish we had the time and resources to make house calls and help them install our product and find and remove the real hum source.

So our answer has to be no – we are not working on fixes for hum by changing the PurePower electronics because we are absolutely certain PurePower technology does not, and can not, cause hum.
