@noelpastor I’m in south Florida in the winter where I have the 006. If you're nearby, I suggest buying the X-30 on Amazon, breaking it in, and bring it over to my house to compare. If the x30 lost the competition, you could return it within 30 days.
I can also offer you this (tortured)reasoning. I extensively compared the Holo May to the 005. I concluded they were similar and in the same class. The 006 more resolving and closer to live music, the May more vinyl like and sweeter. The 006 is better than the 005. Therefore, if the May is equal to the x30, the the 006 should be better.
