My opinion it that most of the magic of Sony's sound comes from software tuning. I am even of the opinion that the positioning of Sony Walkmans is done through software, hardware is an addition. Sony just went this way, they put a tremendous amount of work into software tuning, that is their know-how and they have been using it for years. Personally, I have not tested it, but there was once a thread on the Polish forum in which a user with WM1A got 5x cheaper A55L for testing. He didn't like its sound compared to WM1A, started looking for ways to improve, and found the mrwalkman mods. He applied WM1A soft to it and was shocked at the scale of the improvement. He even stated that now the A55L sounds exactly like the WM1A. In general, the topic was whether Sony was making a fool of users because of this
Probably Sony'team is on top of the market for sound science, but concerning hardware to be able to produce in a reasonable size volume DAP that offer a 40 hours continuous playing hires flac 24/96 files looks also just amazing. Maybe a Class D amp seems to be also a Sony's exclusive ability, that allow to produce more music than heat (and probably less sound degradation).
I really like the FIIO M17 or the Centrance Ampersand I already own, but there is nothing else on the market with these 3 mains figures :
-> at least an impressive sound quality,
-> a 40 hours playing hires files timelife,
-> less heat and more music (life time/quality).
At this stage, as I already enjoy the WM1A, I still imagine using a WM1ZM2 or even a WM1AM2 with my Vision Ears EXT/IE900 and a Centrance Ampersand amp to switch sometimes to a DCA Stealth.
With the manual, I can't guess if there is still the limitation/incompatibility between the WM1A/Z M2 set à BT LDAC DAC mode and using USB-C to external DAC+AMP.
