I've ripped my whole CD collection with dBpoweramp to ALAC, but as soon as I use some "bass heavier" EQ on my iPod classic (6th gen), I can hear quite loud sound clipping (in more bassy sections of tracks) instead of deeper bass. I was searching for solution to fix this and the answer was to lower the gain of songs (using iTunNORM tag). The only way to do this is by using iVolume, because mp3gain (also AACGain) and all other utilities doesn't support ALAC. This could be fine, but the problem is, that iPod firstly applies the EQ (which distorts the sound) and after that applies the iTunNORM tag to decrease the gain -> the result is just distorted quieter sound.

I was also looking on WaveGain (CD -> wave -> WaveGain -> ALAC), but it looks like, there's fairly a lot of bit loss - which means WaveGain-ed ALAC files aren't lossless anymore. I wanted to ask, if there is any lossless way to play my ALAC files on iPod without distortion with EQ on? = do you have any idea how to lower the gain of tracks without losing quality?
