Yes, your ARC results are just what I expected when I ran the program with a single AHB. The output of your speakers is just as it should be. Thanks for sharing.
I have run ARC with a single amp in the middle and in hi gain positions, same results. I have sent past results to Anthem and no real response. This recent result was sent to Benchmark and I'm hoping the results will be shared with John Saiu (spelling?). I've also run ARC using each of the two amps, both produce the same results. I think the amps are fine and it's some quirk in my system. My primary LP is 14 feet from the speakers so perhaps that is a factor, who knows. I love the little amps, you won't be able to resist getting a second one, if only for the symmetry.
