How reliable is PS audio equipment?

I would think in 20 years, the advancement in technology would necessitate the want for a new preamp. I would like to believe that is the direction that Paul was coming from. 

When the clock strikes 20, masked audio henchmen break down your front door and take it away.

Yes, watch out for henchmen wearing masks.

No issues with PS Audio. Own their phono stage and some power products. Have visited their facility in CO. Occasionally watch his Youtube videos. Nothing but good vibes. YMMV.

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.
