It might very well be the DAC doing the work then, or maybe the placebo effect is just making me pay more attention to music I first heard years ago and I'm picking up more :)

Thanks for the information though, I'll do some A/B testing to see if it makes any difference to me.

Just the Hifi level is probably enough for almost any system. I also noticed a huge difference coming from YouTube and Spotify on the Hifi setting in Tidal. I didn’t bother with Master as my ears aren’t that magical
