Let's not go down that route.
The O P is asking about Digital Music Players, he has not asked for alternatives.
If you cannot answer the OPs question then don't reply.
Thanks.
It's helping if there's a better alternative that's far, far cheaper ( smaller and lighter i might add and heck some even smaller than the dragon fly) 100 quid opposed to 1700 quid or 500quid and can drive alot of different headphones. The OP probably has the best portable player in his pocket already, does exactly what he/she wants and more. With access to all the streaming services allowing downloadable offline playlists for when out and about and data is an issue. The DAC decodes MQA and DSD, heck some phones even have SD card slots, though many devices have ample internal storage these days.
This could go across many devices not just the one that may be thrown in a draw in 3-4 years (if not before). Perfectly viable option IMO! AND! So i did answer the question im just not trying to wast their money!
I just happen to think in this day age portable music players are non-sensical hence the biggest player on the market (apple) no longer sells them and companies offering these tiny little dacs for potable use. (But i wasn't going to be so rude about it),
SO NO NEED TO BE SO RUDE moderator or not! My response was far more helpful then "i have one and like it" so very helpful indeed (no offence to whoever said that)
Back to OP question best purpose-built music players on the market bar none is one of the sony walkmen android players, come in at various price points and all pretty much work the same, some only available as imports out of Japan for some reason but have English selectable user interface. Techmoan has a lovely review on his youtube channel of one. Ive listened to a few and its by fair the best sounding £ for£, If it has the functions you want/your after
The downside with any of these players interfaces can be somewhat sluggish but that may have changed in the last year since I looked. And many are built around the android platform if your bothered by that. (some are)
I stand by alternate solution and i would look into it, John Darko on youtube has a very comprehensive video about this solution on his channel. No harm in watching a video to see if the solution is for you.
Other options listed above are a good shout too if you must have a stand-alone player.
