IPOD Video sound quality with Rockbox

<< < (3/3)

soap:
"Unforgiving" is such a subjective term.  
A 16 Ohm phone, as PHK Brasil's RMAA graphs show (in "Part 2" of his linked post), without the EQ "fix" has 3dB of attenuation @ ~35Hz.  While this is not great, it is not going to be noticeable to many if their headphones don't go down that low.  3dB of attenuation = a halving of energy = well you can turn your Rockboxed player down 3 dB and see just how noticeable it is.  (Not very, your ear isn't linear in its response to energy.)

A 16 Ohm phone with the EQ "fix" doesn't have 3dB of attenuation until < 20Hz, which is outside the reasonable reproduction range of earphones (regardless of manufacturer claims).  Mind you, when looking at the graphs, that 1dB of difference is widely considered the limit of human perception, so you can safely ignore any graphical fluctuations less than a couple of dB.

streetviper:
OK. Has there ever been a (objective) comparison of the two players with Rockbox or a testing of the iaudio like the one above so I can compare myself?

carmenm:
I have a question concerning the bass on ipod 5.5g. I have a h340 and an ipod and clearly the bass are a lot better on my h340. I cannot really compare as the settings are not the same on both(didnt update for a long time on my h340). i have 14(goes from -8 to +8 on my ipod) for bass on my h340, with everything else to default and no EQ. And whatever i do i cant manage to have the same sound on my ipod. Isnt it possible to have the same bass quality (E500PTH ) on ipod? if it is can someone point me to a configuration to do so.

Thanks a lot
