Well, since my $7500 Dennis AVP-A1 pre-pro doesn't have the AirPlay (which I love) that most $400 AVRs have these days, I decided to add the little black $99 Apple TV box to my AVP-A1 via HDMI.
Now I have the AirPlay (which I love) to stream music from my iPads.
The Apple TV also has Netflix playback. It also has Hulu. But unlike my $100 Panasonic BD player, the Apple TV does not have Amazon Prime Video yet. It may have it in the future, but not now.
Anyway, the weird thing with the Apple TV is that the volume level is 6dB less than my other sources on the Denon. So I had to increase the digital source level to +6dB for Apple TV. Now it's perfect.
I think SQ is excellent.
