The reason you find a difference in the PCM output has to do with the fact that the synthetically created Huffman data in turn causes overflow conditions in the subsequent IMDCT calculations due to MAD's limited fixed-point representation.
Would it perhaps be better to clip at less than full scale during requantisation ?? This would reduce the chance of overflow in the IMDCT routine (which potentially corrupts far more data).
