I'm a noob audiophile and I only recently started with this hobby. However, I have gone through Tidal, Qobuz, Apple Music, Youtube, Amazon, and the other streaming services. What I have discovered is that the recording format doesn't really matter. It could be FLAC 44.1 or MQA and if the master quality sucks, then so will the sound, no matter how you rip or download it. So that means the reason why CDs typically sound better, is because most of them were mastered properly! The stuff they are throwing up on these streaming sites like Tidal are typically remastered versions, and these remasters are done my monkeys in a sweatshop in Mongolia somewhere! They suck! And that's why streaming sounds worse than CDs, not because it happens to be in MQA or FLAC or AAC or whatever. The master quality is the biggest issue here. That's my 2 cents on this topic. Feel free to disagree.
