just finished the install of rb not enough time to make a comparison
but from what i can tell it does indeed sound more neutral than the stock firmware.
i spoke to ibasso asking them when the next firmware was out for release and they
replied" there is a lot of new changes to the new firmware which is why its taking so long.
i wonder if the new firmware will be on par with rockbox? we shall soon see hey.
i hope they can make the necessary changes to there software so people can enjoy
the neutral sound that everyone is striving for in this community .
rockbox is very neutral and very natural sounding to me .
i will do a follow up review of my comparisons very soon ...
good job people .......
