the x1 ii is FANTASTIC! i've been using it ever since i got it as a gift for christmas 2019 and i've never looked back. it's absolutely perfect for my use case. while the interface does lag quite often i'm used to it at this point and for the original retail price of about $100 (maybe less?) it wasn't too bothersome. i do think it's discontinued by fiio now though and they might have better models out now but i wouldn't know - if you're not satisfied by the new models and you can find the x1 ii secondhand and functional, i highly recommend it!
