hmm after reviewing the video again, this time all the way to the end, I've found that my solution was in the last 45 seconds of his 10 minute video. My bad.
for those that don't want to watch it, after importing the model with your options selected, hit enter to voxelize, and add a bunch of resolution. For whatever reason, hitting enter and typing in a number (try somewhere in the millions, mine looks fine with 500,000) doesn't smooth the model and preserves the hard edges.
Thanks guys!
