Did Another run of the new A.R.C. yesterday. No issues at all. According to the firm ware update info, was more related to wireless issues with play fi.
With music it seems more fluid or blended. I like the Anthem logic setting {all channels minus center}. Gives a massive center image yet the backing voices and percussions creep in eerily to the rear. Much larger than basic stereo setting but very similarly balanced with my 5.2.2.
No movies as of yet.
