reason i am asking is because i think there is but i am a bit biased since i think my viewing experience has changed significantly after my recent AVR and Dolby Atmos (A60) upgrades.
The audio quality depends on the source material. In order to answer your question, you have to find out what's actually being provided. Most streaming services provide only lossy Dolby Digital soundtracks. Many rental Lionsgate Blu-ray titles also provide only lossy Dolby Digital soundtracks, not the lossless Dolby TrueHD soundtracks which are available on purchased Blu-ray discs.
also how do i know if im getting Atmos quality signals from movies with Atmos soundtrack i.e. Insurgent. seems like all i see when i hit INFO is Dolby Digital + Dolby Surround (using a sony BDP S6500 blu ray player).
thanks again in advance
Your AVR is reporting the type of signal that it's receiving. "Dolby Digital" means that it's getting a lossy DD signal, not lossless TrueHD.
Depending on the disc you're playing, you might need to change two settings in your Sony BDP and/or you might need to disable the speakers in your TV (not just mute them).
The two relevant Sony BDP settings are
Digital Audio Output = Auto (the default)
BD Audio Mix Setting = Off (NOT the default)
Also, if the TV's speakers are enabled, its EDID might be visible to the player, which will downgrade its output to match the TV's capabilities instead of the AVR's.
When the receiver is fed an Atmos soundtrack, Info will show "Atmos" in the left-hand side of the graphic display at the bottom of the screen. It will not show that it's receiving any particular audio channels. Also, a display saying "Dolby Digital + Dolby Surround" means that it's getting lossy Dolby Digital audio, not the lossless Dolby TrueHD audio that's needed to transport Atmos.
