Another vote for Medici TV, my wife has a subscription and I watch occasionally. Like everyone, I have my foibles and only really enjoy listening on LP or some Cd's loaded onto my server. I do enjoy going to see the Met and Royal Opera streams in the cinema.
I find there is so much cheap Opera on vinyl now, the best option for me is buying vinyl in Charity shops. Fortunately or unfortunately, Classical Vinyl, particularly opera, is almost valueless second hand, at least in the UK. I find really good box sets available for £4, in the charity shops.
