To expand on Gabriel's comments: one of the main differences between 3.87 and 3.91 is the treatment of high frequencies (via the "ATH"). If you insist on using -k at bitrates around 140kbps, (a bad idea), you will probably have to try some of the differeent ATH options which downplays the importance of the high frequencies. Otherwise lame will use a lot of bits trying to encode the 16-22khz range. It represents 20% of the spectrum, but probably only 1% of the sound quality!
