You may find you prefer it with the --no-peaklock option, or even 
with --crispness 5.

I perhaps foolishly didn't include a standard crispness option that only 
does the equivalent of --no-peaklock, because that wasn't preferred to 
any of the alternatives for the examples in my informal blind listening 
tests.  (Instead the default settings tone down the amount of peak 
locking gradually as the stretch ratio increases.)

Yes.
