As for the streaming service, I like convenience, so between Tidal and Qobuz, is one more convenient to use than the other?
I used to be very anti Tidal due to their higher pricing and absurd MQA requirement for hi res, but both of those things have changed so music selection may now be the biggest differentiator between the two. I will say as a Qobuz user I find their search function subpar. It works, but often I search for things I know are there and they still don’t come up — very frustrating. I’ve since learned how to work with it, but it’s an unnecessary weakness that Qobuz frustratingly seems unwilling to improve. It’s not a huge deal and overall I’m very happy with Qobuz, but I mention it because you’re asking about convenience and this is one area — along with playlists if those are important to you — that you might want to pay attention to as you compare the two.
I totally respect your rationale for wanting to avoid PRC products, and I think you’re on the right track with the Zen Mk3 especially if easily ripping CDs is important, and you’re also getting their excellent Sense app and customer service that are very significant pluses. And of course sound quality is among the best in your price range. Hope this helps, and best of luck. If you do get the Innuos I’d be very interested in your thoughts as I’ve also got a Zen Stream and am also strongly considering the Zen Mk3 as an upgrade.
