That's the waveform that reveals the most with sample problems since it otherwise lacks overtones. I will check again however and make sure they split at a peak or trough. The PCM output from a preceding track should be butted right up against the output from the following-- nothing added or deleted (with the exeption of what gapless headers indicate to be stripped). > Not really on-topic, but "compared to other MP3 players" is the key > phrase.

If you want a ridiculously loud player, then a Gigabeat S (way overpowered) is your friend and has no noise issues from digital circuitry like the Sansas (that I've observed).
