"...They have been very quiet"A launch like this is hard. Esp. for a non-domestic company of the scale and ability of Qobuz. When I asked a couple months ago, their customer service replied "We hope open by end of year." I'm guessing that's as good a guess as any.
I've not listened to any 24/192 streaming so am not informed to comment on that particular delivery mode. I have listened to alleged "hi-res" audio files from HD Tracks - other than what to me sounded like monkeyed EQ across the frequency spectrum, mostly in mids, for me the difference in sonic "quality" between that and redbook is modest at best.
Indeed there are clear-headed perspectives if not analyses about the 'value' of so-called "hi-res" music reproduction (including this, and this). These may be helpful as we try to discern real vs perceived differences in what the streaming services offer.
Wrt MQA, there's growing opinion if not evidence of that being a total bucket of bullsh!t. Archimago's usual measured and thoughtful analysis is a good source, and here's another from someone on the ínside, so to speak.
