Every once in a while I go on a 5-10 cd bender on ebay, it costs my like 20-30 bucks usually.

If you really want to give it a go, forgo audio streaming and CDs and get a subscription to the Met Opera’s streaming platform (which has a seven day trial period.) , They stream audio in 16bit 44.1, so not terrible. Opera is theater, so it should be seen.
