I love all these amp and speaker recommendations. It's like recommending a paint job on a ship with a big crack in the hull.
+100 on the posters suggesting the digital chain drastically needs an upgrade before any other gear should be considered. Airplay is far from optimized. A good wired streamer and DAC is absolutely the next step. It would be challenging to determine what else to do until the source is better optimized.
Tidal is supposed to be rolling out non-MQA high resolution and so make sure your new digital rig is capable.
