After several days of intense thinking, I have decided not to get a custom cable for my Utopia, at least this year. For now I would like to get a few more tubes for my Liquid Glass and just take the time to appreciate and grok all the fine stuff I already have. But I know some time next year, I will get a custom silver XLR cable, for my incredible Utopia.
You could always cut the cord shorter and place plug of your choice on it.
Then get a female type connector for the discarded section to make into an extension cable.
