If you ever want to explore Indian classical beyond vinyl, CD and streaming, you’d find a treasure of old live performances from various festivals (Kashi, Bhopal, Delhi, Ahmedabad etc), as wel as studio recordings and radio programs on archive.org. Some are in FLAC, most in Mp3, but you won’t listen to these anywhere else as they didn’t get published by the labels.
Within streaming, try HCL Music, Classical Saregama and Ragya which are dedicated to Indian classical music. Especially Ragya has relatively limited, but excellent collection from young artists as well as less known senior artists. That and HCL music are great sources to go deeper into the genre. As are some Internet radio stations like Sandesh Radio and Sangeet Samvad. On the other hand, the Internet radio station Shanti Shanti run from Paris has the best sound quality and plays most of the Indian classical legends.
For vinyl and CDs you can look at eBay and old resellers around as most of it is out of print.
