Looking at Black Friday Deals in Aliexpress the Fiio M21 is £193 and the Shanling M5 Ultra is £293 which are both excellent prices.
What I would interested to know is about integrating roon arc into the Shanling and whether it is a (software) flexible as the fiio appears to be. Not seen that the M5 has a desktop mode either.
Any other thoughts are welcome, Ill be using Hype 4 IEMs as well as HD650 and Edition XS headphone
