I don't think it will take any longer - actually it should be faster. BIAB converts the regular RTs into WAVs. Since the Audiophiles are WAVs, no conversion is necessary. Are you going for more quality or faster generation? If faster generation, you can convert your existing RT/RDs to WAV. It makes a big difference on older machines.

I would guess that using USB for the audiophile would be somewhat of a bottleneck.
