Fiio M11 Pro

Have the M11 Pro, don't care for the sound signature so much and my one also suffers from the display having issue as do others. This where the display has a large rectangle ghost image right in the middle, many attribute this to the heat from playback and charging, personally I believe it's more related to poor QC and choice of display source.

Obviously this issue does not effect SQ, however it's still really irritating as the M11 Pro is hardly a bottom tier product, something Fiio should have paid more attention in the first place. Worse it takes time to develop as what I believe happens is as the adhesives in the display laminate cure fully over time the distortion forms.

I don't think that Fiio designs and produces poor products, however they do need to slow down and get the details right at this level...

Depending on your AMP on the DX220 it's either a side or upgrade. Maybe a downgrade if you have amp8ex or better custom modded one.
Speed performance is a definate upgrade. Both are rootable devices.
If you like the Mango mode of the DX220 then the Fiio doesn't have that. The closest it comes is the pure music mode which just stops some background processes and prioritises the fiio player. Both sound better with Neutron to my ears, especially if you use eq.

Cough Cough from which site 😂

Not sure on your budget but the Shanling M6 Pro or Hiby R6 2020 are a great alternative if you need android (or bigger brothers M8 and R8 for TopEnd) If you don't need android then Cowon Plenue 2 MKii or Plenue L keepjng in line with the above costs HighEnd/TopEnd.

Only modules I rate are T01 and E02 if you can get one with one of those instead of the most common A01 and having to fork out for another module. Definitely a speed increase, sound with one of those is an upgrade over AMP1. Against AMP8 maybe a side grade.
