Interesting, that's now the first report of NAD receivers shutting down we've gotten, other than the original comments reported from some store's salespeople. The Tritons are really easy loads to drive, can't imagine why they would have an issue with our powered tower speakers in particular. We used a larger model at a trade show event last year and it sounded great and had plenty of guts. I believe that was on a soundbar system, so not exactly the same.
