I think he's asking if he should have ordered BH5. I'm a sucker for these upgrades, but unless you have the exact same speaker, one with BH5 and one without, there's no way to perform a comparison. I sold my VMPS RM40s to someone who had another pair. Mine had all the upgrades, and his only had some. He said that mine were better, but he had both, so at least you can trust that opinion.
