That`s good.

2. rolloff_speed set to "slow", so the sound become less "tight". (this was hardcoded in 1.2.0 firmware, 1.1.0 was "fast" but see below)
Great, I`ve always used slow roll-off.

Just to be clear - RSU 1.0.0 is based on official 1.6 firmware? RSU 1.1.0 & 1.2.0 are based on official 1.2.0 ? If so, then going to try RSU 1.0.0 and 1.2.0 sometime soon. 
I`m guessing RSU 1.2.0 will be better because I liked SUEX 1.2.0 sound. Still, despite RSU using pre-installed theme, I`m not sure if I`m going to like UI more than Mango but we`ll see wink.gif
When he said "this was hardcoded in 1.2.0 firmware" I'm pretty sure he means Rockbox 1.2.0, not SUEX. If you saw him say somewhere else that it was based off of SU EX then let me know! Because that was my favorite sounding firmware BY FAR! smily_headphones1.gif

Rockbox is definitely not as east to use because the UI isn't labeled. What I mean is it doesn't tell you where to go to navigate to different parts of the UI when you are on the Now Playing screen. There are a plethora of themes you can download, but Mango will always be easier to use. I mainly use Rockbox for its Replaygain capabilities.

anyway you could download this rockbox update(1.2.1) - https://mega.co.nz/#!LcE0gQQT!ACiWGUwu9aDbgR83JEUcU4Hrj1H5o8Cu5ciUvtKnR8E

and you be able to choose the rolloff speed "Settings -> Sound Settings -> Roll-off speed -> Slow/Fast"

 

This update can applied for any RSU version.

 

This rockbox build includes changes provided by ArgelErx(code reorganization, most of patches for DX50), Cholero (modern ui).

Since I have 1.1.0 I can just replace the files in my Rockbox folder, correct?
