I mentioned that no amount of fiddling with the treble and bass would correct for the loss of sound in the "phantom center", at least in the time I gave it last night. SallymaeHogsby got it right a few posts ago when she said that classical music sounds "gutted". I was listening to some Vivaldi today on the 3.0 fw, and the solo violinist sounded a little washed out. If that's how it's supposed to sound, I'll stick with "wrong" because all of my other DAP outputs sound just as wrong, and much better to my ears. I dunno what to tell other people, maybe my unit is defective in some kind of way that only exhibits itself when running the 3.0 fw?
Strange. I have the opposite effect with FW 3.0. Everything in the center is more pronounced and can be understood more easily. It was more difficult on FW 2.14 where center material seemed to take a step back, was further away and seemed to blend together with left/right information: a fairly flat experience.
FW 3.0 sounds wider... but deeper as well, to me the stage is less shallow. And I continue to marvel at the "directness" of everything in the center and the precision with which it is rendered.
I don´t know if it´s possible that your unit displays a different character when both use the same firmware.
