Try Sound Unlocked 1.3.3 @ FLAC mode and You will be probably even more surprised
For me most of those sound explosion FW`s sounded artificial. I also tried other custom FW`s & rockbox but so far SU has the cleanest and accurate sound.
Also, after some testing I found that with my Fidelio X1 I prefer different setting than with my external amped speakers.
X1 (head-out) --> FLAC-only + IRR OFF + CPU default + mid gain
Speakers (line-out) --> FLAC-only + IRR ON + CPU 312kHz
With X1 settings speakers soundstage felt littlebit too distant and thus not so clear instruments separation/positioning.
Differences are small though but for my ears noticeable. And I have quite cheap modified speakers system also so it is probably because of that sound reproduction "quality".
