Interesting, I had not thought of using an amp with my phone. Thank you.
Fiio x3ii or Fiio x5ii
I have a set of Oppo PM-3 cans. Is the Fiio x5 gen 2 worth the $100 more than the Fiio x3 gen 2? The increase in memory means nothing to me, I am purely asking about sound quality. All my music is 24/192.
