Many thanks - I actually have an older Denon, and just wondered if a newer one would help. I had bought the Samsung TV expecting to connect everything to it and send the sound from it to the Denon, but that creates lip-sync issues (poor show Samsung). I can route one source through the Denon to the TV via ARC and that's fine for the BluRay and for the sound from the TV, but I have one more source (Sky Q) and that has to go to the TV and then to the Denon. I can eliminate the Sky Q lip-sync issue by routing the sound from the Sky Q box in parallel to the Denon, but then I have to manually switch the Denon to use that sound rather than the sound from the TV. It's a small nuisance, but would be great to eliminate. I will think again about Harmony, but I really like the minimalism of the Samsung remote. Thanks again.
