I'd say you've got it bad! I don't really know the 401 well enough to comment, having only heard them at shows.
As for VTA, it's best to experiment by ear. You can use a little bubble level on the headshell but dead level doesn't guarantee the best sound. Try it a little tail high and then tail low and you will hear which is best. The angle that the stylus is glued to the cantilever varies from sample to sample, so the best VTA will vary.
