Qobuz’ streaming service of course requires net access just like Spotify & Co do. Maybe they allow some local storage for that. I think Nick(?) will be able to answer that. I only use their download shop which is often a lot more expensive.
I did answer the question, but I guess since I linked the actual sites, the board thought it is spam.
Interestingly that I find Qobuz pricing often very good, but maybe that’s because of the subscription I have. About a year ago I picked up the new Andris Nelsons Shostakovich cycle with the Boston Symphony Orchestra (19 CDs worth, all symphonies & concertos) for €10,99 in high-resolution sound, including booklet. That’s a lot cheaper than I’ve seen it anyhwere else.
