Yes, Qobuz definitely needs to work on their customer service. I'd saved a link:
but now it's different, but I can still get to a contact point via a lot less trial and error.
Regarding the service, I didn't like their Windows interface (cell/tablet apps always seem limiting to me, vs. a full screen and the information/options it can show) - and in the beginning I was accessing Qobuz via the Bluesound Windows program, yet another serious limitation.
I ended up buying the Roon software, and that got rid of all the problems I was having with the Qobuz program. As regards music "hanging" sometimes while listening, I recently replaced my DOCSIS 3.0 cable modem with a DOCSIS 3.1 version - same speed - and all those problems disappeared (DOCSIS 3.1 isn't just helpful with getting higher max speed service if your provider offers it; it's got performance improvements that make any bandwidth tier more responsive).
I realize that the Roon software purchase is expensive, but they've got a subscription plan. For discovering new music related to your tastes, organizing everything and much, much more, I wouldn't want to be using any of the current streaming services without it.
I've seen one or more criticisms of MQA, here, and it just doesn't jibe with my experience. Maybe I've got a "better" sound system or just more inclusive tastes, but I've listened to some MQA music and didn't have a problem. Of course, much more depends on the processing in the front end of the process (recording and mastering equipment and choices), but on a good, flexible system there shouldn't be an issue. If people have objections from a simply mental pov (numbers people) without much regard for psychoacoustics, you have my sympathies; for me it's all about the music.
