How reliable is PS audio equipment?

I have been happy with their P10, P20 and Stellar Phono Stage no problems of any kind.  Before that I had an integrated on loan for a while that was several years old at the time.  It worked fine too.  Maybe all of this stuff had the 20 year switch turned off. 

PS Audio is end game gear for me. I love my preamp, DAC and transport. Heck, I'll be lucky if I last another 20 years. 

Have alot of ps audio equipment including fr30.talked with cris and paul took the tour in Boulder was treated with royality.ask where and what was made.saw many prototypes they were not afraid to disclose secrets and sources. It is true it have bought some of thier refurbished equipment so they must have a rare failure like all electronic equipment everywhere.paul has been involved in alot of development and history. His vidioes are informative.i wish more engineers would do educational videos and answered the common man's questions. There new product is designed by a nasa engineer.great customer service. Highly recommended.thanks for the memories paul and chris.

PS Audio did have some build issues in the past when their gear was assembled in China. My Chinese built Premier Power Plant failed within a year of purchase. PS promptly replaced it.  The P5 Power Plant that replaced the Premier is made in the US and was built like a tank as is the P12 that I bought to upgrade from the P5. I see no reason to believe that PS gear has any specific life span.

i just replaced my 31 year old Conrad Johnson PV-12L with a new Backert Labs Rhumba Extreme 1.4.  The CJ was not built to the current PS standards but the only work I needed to have done to the CJ was cleaning contacts on the Selector knob.

Perhaps the "20-year" clock is when PS thinks it needs to be serviced and recapped. Which, in the greater scheme of things, if your hi-fi component only needs to be serviced once every 20 years, I'd say that is pretty damn reliable, especially if it means another 20 years of performance after said "tune up." 

I would say the great thing about a company like PS Audio is that they're made in the US, and you call them up and get someone on the phone, and they can fix it. However, this isn't the case with many companies these days, as we all know.
