Another approach is to look at why there might be a DC offset in the first place. One of the most likely culprits is samples or wavetables that do not end on zero.
If your original samples/wavetables do end and start on zero, try the Remove DC option in the Modifiers of the Wave editor to try to balance your original samples and wavetables.
When replicating, another trick you can try is to alternate the phases of the copies. This can help prevent DC offsets if they're all the same sign. To alternate the phases, you could put a Level onto the Input to the Replicator and set the Right and Left fields to alternate between 1 and -1, for example:
(?VoiceNumber mod: 2) * 2 - 1
