I've put all my music through "Analyse Audio" and it's tagged for ReplayGain.
In DSP Studio, I set up the following:
- Check Volume Levelling
- Mode - Track Based
- Adjustment - Automatic based on Current Playlist
- Set Clip Protection in the relevant box
Whether by design or good luck, I've not had a problem.
I also don't drive my amp hard. So, that's another potential point where sound can clip.
Have you had a look at the Analyser in DSP Studio to confirm that the issue is with MC and not with your amp?
