Don't use WAV - you will lose album info...
I'd use AIFF or Apple Lossless.
Check Benchmark DAC1 wiki guide for iTunes setup (settings for bit transparent playback) and keep checking regularly in case a big crops up with a new iTunes version (you'll get automatic updates every month or so but sometimes a new version introduces an error)
If you turn error correction on then iTunes is apparently bit transparent when it burns your lossless files.
