Congratulation what an amazing collection.

which one is worth to get first?

I had fiio k7 I don’t think it sounds great with full size headphones but really good with Iem.

Can you share your impression of Mirai compared to U12T and Sony Ier m9 ?

Does it sound lean thin and bright or thicker and natural in general?

how is the bass and vocals does is it sound like Audeze lcd 3? I’m still dreaming of iem that sound like lcd 3.
