yes, DI box. your choice of active or passive, powered or pure
transformer, or variations of the above. but apart from the clipping you
will get some weird frequency response changes from the impedance
mismatch.

I would do this. less noise, less disk space, less load reading it back
for playback (makes a difference on my marginal harddrive setup, may not
affect everyone)
