OK, that makes sense. I thought the tablet was pulling data from Spotify, then sending the audio stream to the AVR. But if the Denon is getting the data directly from the interweb, then that's as good as it's gonna get.

I was having weird issues between Paypal and Spotify yesterday when I tried to upgrade to Premium. Spotify kept giving me error messages. I finally got a receipt from Spotify today, so I'll check the audio stream for bitrate tonight.
