I know guy who bought one at a dealer shop and then sold it shortly after. He had more difficult load speakers not designed to work best with tube amps. So it was just a system mismatch nothing wrong with the amp itself.
I think many people just fall in love with tube amps and end up with mismatched systems. Primaluna seems to have good distribution in the US and offers good value so I think there are more cases with those mainly because there are more of those out there than most tube amps.
