That Rotel also blew up when being tested into low impedances. Clearly took out a channel and they only had a single channel left to run tests on. An amplifier that almost doubles down, blows its fuses and then ceases to function is a fail as far as I am concerned.
That said, I love Rotel gear. Generally, it is built beautifully and pretty much always performs better than spec.
I ran some tests only yesterday on a little vintage integrated Rotel (RA-930AX) I'll post in the reactive load thread today if you're interested.
