I don't know how much of this stuff is system dependent. I really can't tell you how much of a difference disabling analogue outs or wireless makes.
I can say this, tough. With TT 3.0, you can use an SSH program to switch the display on and off, on the fly. I use my iPad to do this. When switching the display on and off, there is a definite audible difference for the better when you switch the display off. It's as though a slight veil has been lifted.
Of the two, I'd say that EDO is easier to deal with. It installs from the Touch itself from the 3rd Party App menu. Once you install it, all available changes can be made from the Touch, through the menus. When you want to uninstall it, you just go back to the menu and choose to uninstall it. Just make sure to uncheck the option to automatically reinstall it after an update, otherwise it will just reinstall.
TT 3.0 is a bit more involved. It requires a terminal program to transfer files to the Touch. It isn't hard and the instructions are pretty clear. All adjustments and available options are accessed through the use of the SSH program. The upside is that removing it requires nothing more than a hard reset.
Oh, TT 3.0 suggests that you change an option in the server software allowing the decoding to be done on the server. Be aware that if you are running wireless, you network may not be able to handle the bandwidth necessary for hi res files; the operative words being "may not."
