Yes, I was referring to mulit-band eq. I never did try it in 2.14b (heck, I don't even use bass/treble), but some people claim it din't work all that well so maybe that's why it got dumped. Either way i'm not going to lose sleep over it.
I tend to rotate my earphones quite a bit, so I really can't say anything about whether the sound has changed for the better or worse, but I think I remember James/Joe mentioning that nothing has been done since the beginning to alter the sound - other than fixing decoding bugs (mp3, ogg, etc).
Been really stable so far, and really the only negatives I can say are minor quibbles. Album art which is over scaled and getting cut off on the sides, and looking through the firmware files there is a shade graphic that should darken the background when displaying info/lyrics (kinda like volume) that doesn't seem to be active. Makes reading the tag info over top of the artwork really hard (I might add this to bugzilla).
All in all however, a great job by the Fiio engineers, and I'm looking forward to good things to come.
Cheers.
ps. I should have my theme updated by the weekend.
