My Yamaha RX-A3080 is the current year top-of-the-line, so, hopefully, the kinks may have been worked out. I have absolutely NO understanding of "robustness" as it applies to HDMIWell, hopefully it works for you with the particular AVR you plan to use - it works OK for my Arcam. My experience with my Denon AVR into the Lumagen input was one of frustration, frequent drop outs and resyncs. That was almost a couple of years ago though, with one of Denon's first 18G designs. Not wanting to put words into anyone's mouth, but I think @jrp was referring more to issues of HDMI robustness than subtleties of marginal picture quality variation due to unwanted processing.
