You’re still getting a clipped MQA stream when it is showing “TIDAL FLAC 44.1kHz 16bit 2ch”.
In this link, Tidal “HiFi Plus” Introduced - #16 by Terry_Stone, read the post and the one immediately following the findings I published that @wklie was kind enough to explain. That should marry with what you’re seeing.
There are further tests ongoing to try to get a definitive position for the new Tidal hi-fi tier, but essentially, you’ll not be getting what many people had hoped for or thought they might be buying.
It’s starting to become moot now for people like us in Oz as Qobuz has launched and is offering std and hi-res PCM.
