How's the E200 port for day to day use?

This is very true, there goes me getting confused again :)
Llorean:
Either way, 50% in the original firmware isn't the same as "halfway between mute and maximum volume" in Rockbox, and should not be expected to be.
For one, our range is quite different (we go a LOT quieter than the original firmware) and for another the original firmware has two different scales I believe (loud and normal or some such) so it's quite difficult to say what one level is roughly equivalent to in the other firmware.

Whoa. Asked what I thought would be a simple question. Sorry for not being more precise.
LLorean, I had forgotten that I'd just reflexively switched the music volume level to "High" on the Sansa even before plugging in any headphones to it. I switched it back to normal.
Now the volume levels at the higher end of the scales roughly match up for both Rockbox and the Sansa. I've used Rockbox on an iPod nano before with two different headphones. It just seemed louder to me because I used to listen at a level somewhere much further down the scale, versus somewhere from -15db and higher like I am now. Oh well, could just be me. Sorry if this was a silly question, thanks for the responses.

I think that, given reasonably high impedance (32-64 ohm) headphones, and reasonably similar DACs (comparable output impedance) you should get nearly the same volume on both devices for a given rockbox setting.
The reason I think this is because 0dB is line out voltage (I think), which should be the same on all DACs, which would mean that ignoring differences in current supply from different DACs, you should get the same loudness.
Obviously, if the DACs have different impedances, or different headphones are used, you will not get the same volume level.

I just received my e280 a couple of days ago. Initially the OF didn't didn't seem to be too bad. Now that the beast is rockboxed it's no contender anymore. Though having experienced some problems in RB the overall stability and usability is great.
I previously owned a 2nd gen. Nano and I quite liked it. Anyway, now I own a DAP in which I am of full control again ;).
The only really flaw I experienced is the hiss noise you can hear when the flash memory is accessed.
Overall e280 and RB is a really great combination!
