Rockbox shouldn't affect the SQ for a player lest something is done with the audio processing code I imagine. This wouldn't be a bad thing if done right on a D2, since even when compared to players renowned for SQ in the past, the D2's soundstage is severely compressed, even when compared to the iAudio U3.
Gapless, Flash, 4GB+, EQ, Lineout, excellent SQ
- Flash modded Rockbox compatible iPods + LOD (e.g 32GB CF Mod iPod Mini)
- Flash modded Rockboxed iMod
- Flash modded Rockboxed iRiver H320
- Flash modded Rockboxed iAudio X5/M5 (Not through line-out, the line-out of the X5 sucks, with a signal that has a bass roll-off so severe its worse that any of the old 16 Ohm loaded iPods I've seen, and I would imagine that by proxy, the M5 is affected as well)
Gapless, Flash, 4GB+, EQ, Lineout/Digital Out (Same thing), excellent SQ and Optical Output
- Flash modded Rockboxed iRiver H1x0 series.
