PS Audio Power Plant Premier THD Output Results


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.

The Power Plants will display both incoming and outgoing AC distortion on the front panel. Otherwise, a separate AC Quality Meter is required. There are a number of examples here: (http://www.ebay.com/sch/i.html?_odkw=thd+meter&_osacat=0&_from=R40&_trksid=p2045573.m570...) Of course, the meter has to have a range extending to(at least) 125 Volts, to test your listening room’s incoming AC supply. ie: (http://www.ebay.com/itm/Keithley2015-THD-Digital-Multi-Meter-6-1-2-Digit-Harmonic-Distortion-/121629...) and (http://www.ebay.com/itm/Bench-Power-Factor-Power-Meter-Total-Harmonic-Distortion-Analyzer-PF9810-/25...) then there’s this type: (http://www.ebay.com/itm/Amprobe-ACD-53NAV-1000A-AC-Power-Quality-Clamp-Meter-/252722968541?hash=item...)  You might be able to configure something like this, to mount/use in an audio rack: (http://www.ebay.com/itm/Siemens-4720-3-Phase-Power-Quality-Watt-Meter-Analyzer-and-Controller-DRMC-1...)
