I’m not in the DAP market but this seems pretty solid for $200.

The problem with low-end DAPs is that they are freaking slow.

This isn’t my review, but this product looks really interesting as a potential DAP buyer. It has Android 13 and is pretty compact compared to other DAPs. This was the only video review I could find of it. No balanced output, but if you’re using it for IEMS, that doesn’t really matter. Snapdragon 665 chip

SD card too

It also has the Google Play store, so even if this doesn’t support SRC outside the box, you could use UAPP and get SRC

The only thing that is kind of sketchy is the battery (2500 mAh) and the Cirrus Logic DAC chip, but I presume that this doesn’t really matter for IEMs.

Also, no systemwide EQ https://www.head-fi.org/threads/hiby-digital-m300-android-digital-audio-player-the-gen-z-music-player-discussion-thread.970428/post-17810474), but you can just use some app to do that for you and that doesn’t really bother me since I don’t EQ
