Huge caveat I forgot to mention: I did all of my listening to the ARC Ref 1 with RCA/unbalanced connections. I have been assured that the Ref 1's performance is much better through XLR/balanced cables than unbalanced ones.
I did not check the Ref 1 using XLR up against a FS 4.0 using RCA cables. It would be interesting to find out, though....
