I wonder if it was a specific problem to Tvad's unit.
I used to have a Perreaux 200iP integrated amp, which is the 200P amp plus an active preamp section. Anyway I remember demoing Martin Logan Ascent speakers with the integrated which are a notorious tough load, and the amp drove them to stupid loud volumes without problem.
It got a little hotter than usual, which was to be expected, because I was used to driving much more efficient speakers, but it was still cool enough to touch...
Anyway I've had experience with Perreaux amps, much smaller and less powerful than the 350P and they have been really reliable.
By the way, they sound great in my opinion. Plus they have a really high damping factor which means they have really good control of the speakers, that's something the N802's will really like. The bass performance of the Perreaux amps I've tried, is the best I've heard in their price range(including Krell), the mids are rich(not in a tube kind of way, but...) and they highs are clear and extended...I have a great opinion about Perreaux amps and their performance...
