I recently purchased a used PS Audio Power Plant Premier.
After installing the unit and plugging in my LED TV, Oppo Blu-Ray Player, and Marantz Pre-Amp I checked the PPP's THD output results and I am getting a 1% THD on the output.
I sent an email to PS Audio and was told that the PPP should be providing me with an THD output of .4 to .5% in order to be working properly. The tech at PS Audio suggested that my PPP may need to have the regenerator rebuilt at a cost of $250 plus I have to pay for shipping both ways so I am looking at a $300 repair bill.
Basically, I would like to hear from any PPP owners to find out what your THD output readings are when you have your connected gear powered on and running through the PPP.
I am a bit skeptical that there is a problem with my PPP as I am getting a THD output of 1% which is only .5% higher than what PS Audio claims my PPP should be delivering.
I am currently getting 2.5% THD on the Input reading on my PPP and about 1% THD on the Output side.
I had sent a question about this directly to PS Audio a few days ago and they replied and said that because my incoming THD was so low that the best I could expect was about 1% THD on the output which is a contradiction to what another employee at PS Audio had told me last week.
Nothing like having two different answers from two different employees from the same company.
I now believe that one of the employees was simply trying to get me to send in my unit just to make an easy $250 despite nothing being wrong with my unit.
I sent PS Audio a reply asking them why I was told one thing by one employee and the opposite from another and they just responded.
Apparently, the other employee thought that I had said that I was getting .1% THD on the output when in fact I said 1% THD. He went on to say that I should be seeing aboutr .4% THD on the output side with a 2.5% THD on the input side which is what I was originally told by the other PS Audio employee....
I think you would need an THD meter and from what I understand those are very expensive so your best bet is to buy a PPP or find someone who will let you use theirs to check your THD.
I am currently getting about 2.5% THD input which from what I have been told is very low.
It will depend on a number of factors including your A/C coming from your wall outlet in addition to the gear that you plug into the PPP. Each time you add a piece of gear to the PPP the THD input values will increase.
When I first hooked up my PPP I had my power amp hooked up to it and it increased the THD by over 0.5% on the input so I removed my power amp from the PPP. It also raised my THD output by that amount as well. It is better to not plug your power amp into the PPP.
