Can anyone tell me which is better in terms of audio video quality Tata sky Binge amazon firetv stick tata sky edition or tata sky binge plus stb. I am currently using fire tv stick tata sky edition and planning to upgrade to tata sky binge plus. Does optical port of binge plus gives dolby output? My TV doesn't have hdmi arc or optical port. Currently using fire stick Bluetooth to connect to my JBL bar 2.1 soundbar. So I was planning to connect my soundbar to binge plus stb using optical port. But no idea about the optical port audio quality.
