Hi Cynic,
The penalty is simply that the noise shaping is a bit more aggressive in trying to conform to the lossless audio spectrum. This saves about 1% of the resultant lossyFLAC size when compressed at --extraportable, less at higher quality levels.
I am currently working on a (very) simplistic psymodel based on masking using the Bark scale. This may be a wrong turn, but it is an option for both the classic method and the --interp-curve method of determining the basis shape of the noise spectrum.
