Spotify (Premium) clearly has the best sound quality among the lossy streaming services (yes Spotify 320 is better than Apple 256... do A/B tests). Spotify Connect (native integration) takes it a notch (or two) higher. Apple is missing out the audiophile streaming devices market as they don’t have native integration with any device. Also Spotify is fast building their Indian content. New albums (even regional ones) appear instantly as they get launched, just like on Apple Music. I can see a market consolidation happening and the Indian streaming services getting bought over or closed down in a couple of years. The only ones that could survive are ones focused on niches (like Saregama Classical).
By the way, does the Marantz receiver support Internet radio, natively? In that case try exploring the world of internet radio channels too - it’s fascinating. This is a space where we could have some quality Indian channels - what exists now is mostly poor 64 Kbps. On the other hand the word has moved on to 256 and 320 kbps standards for Internet radio and FLAC channels are gaining currency too.
