Streamer upgrade advice.

Hello to The Gon Community,

I've come to the point there my digital front end is the weak link in my system. Some years ago, I jumped into streaming with a Cambridge CXN (V1). I think it's still "fine" in as much as it's delivering music that is pleasing to the ears. But, having upgraded the rest of my system over the years, and recognizing that streaming is a different game compared to 2018 or whatever when I got the CXN, it feels like time to "move up in the world". The problem, of course, is the massive number of options out there. Here are a few points I am considering;

1) I am a Mac user and so have always imported digital files using the Apple Lossless codec.

2) My only streaming service is Apple Music and I don't intend to make a change there. I've got plenty of files locally. Paying for Roon or something like that is not in the cards.

3) I don't particularly care about a screen on a streamer. I sit far enough away from my hardware and my eyes are old enough that no component-sized screen is going to be useful.

4) I do like a streamer with some sort of remote app for control from my iPhone.

So, that's where I am. Budget is somewhere in the "up to $2k" range and I don't mind buying used. I'd have already moved to a PS Audio Airlens except that those don't seem to play nice with Apple (only ethernet in and no Airplay compatibility).

Any thoughts appreciated. Remainder of system listed below.
