I totally get it. I owned a ZX300 originally. Sold it, missed it, bought a Fiio M11 Pro, liked it well enough without *loving it*, went back to the Sony UI with a very good deal on a used WM1A a year or two later, and man - one main takeaway second time around:
Audiophiles tend to use the word 'musical' to talk about transducers (iems or headphones) and occasionally DAC chips that walk the line between technicalities and a pleasing timbre on a sonic level, and I can relate to that; but for me this is a 'musical' DAP on a UI level; because it draws a line in the sand for the user - where it insists you don't take up headspace with side-loading apps (and then reviewing the battery life with said apps . . . for godsake what a waste of time). It also insists you don't add to a playlist while you listen. I'm convinced that as more people fall out of love with the direction of 'Big Tech' and the direction that such utterly non-musical apps as Spotify have travelled in (economically, they are utterly wretched for musicians; and the addition of music video tiles have zero to do with promoting the music), that the cult of these non-Android Sony DAP's will only grow stronger. And I'm a realtive latecomer. Some of ya'll were mental for them 5 years ago (and I concur

).
