Have you listened to the intermediate .wav file?
I strongly recommend you do so first - you might even find its just a
weirdness in your soundcard preventing it from playing back the file at its
*true* samplerate, and instead causing it to play it back at one very close
to correct.
Alternatively, you could be imaginging it. 2/5ths of a semitone is a small
deviation - one which I'm beginning to believe most people can't hear [as a
musician of 8 years, with a really sharp sense of pitch, its *bloody* hard
to know what the average person can and can't pick up].
I personally have not heard actualy pitch differences in music converted to
MP3 - just audio-distortion from bad encoders or low bitrates.
