I am jealous about your location. Owning a Takasaki 5" refractor, a 3" Takasaki, a 14" and 8" reflectors and living in the Pacific Northwest... pooh. Are you in Arizona out past Benson? Idaho. Satellite internet then.
A good streamer will cache. I think there is a way to download stuff from Qobuz... when your streamer is up. I'm not positive. Streaming is not going to become prohibitively expensive.
Transferring vinyl... to sound good like vinyl is somewhat like putting together a good sounding vinyl system... but in reverse. So your ADC must be of very high quality or you're not going to get a great transfer.
